What's going on qsu students?
Today we're gonna be talking about
upgrading all of the original stack LED's
on your Technics 1200 turntables.
With aftermarket bright LEDs in the color
of your choosing.
First thing I want to talk about is where
to get these lights.
And the guy that I get them from, is from
Ice Cold Customs.
If you go on Ebay, and you search Ice Cold
you'll find his little Ebay store.
He sells enough lights to replace the
lightbulbs on two turn tables for
something like $12.
And he sells them in whatever color you
can think of.
So what I'm gonna do right now is talk
about what to expect.
Your order is gonna come in a little
package like this and
what you're gonna get is four tiny
teardrop LEDs.
These are for your 33 and 44 buttons.
You're gonna get two rectangular shaped
Those are gonna be for the reset lights on
your pitch faders.
You're gonna get eight of these big
teardrop-shaped LEDs.
And those are gonna be for your power
Each power light has four LEDs on the
So you're gonna get eight, enough to do
You're gonna get two pop-up lamp LEDs.
These are gonna come wired, there's gonna
be two in a set.
You're also gonna get these resistors that
go with those pop-up lamp LEDs.
I'll show you how to install those.
And you're gonna get a little bit of
solder wick.
This is used to kinda remove solder from
the turntable.
I don't use solder wick.
I use a little solder sucker.
Funny to say, solder sucker.
I just prefer that.
And you're gonna get a little length of
It's also gonna come with
piece of paper where you can download the
instructions from.
These do come with instructions.
What I'm gonna do, is kinda give you a
video walk through
of what the printed out instructions are
telling you to do.
Just so you guys can see it and get a
better feel for
it if you're not as experienced with a
soldering iron.
Or reading technical instructions or
anything like that.
So, we're gonna bust into a turntable,
we're gonna put these bad boys in.
We're gonna start with the lightbulb that
goes to the pitch fader.
It's the easiest one to do, so we're gonna
do that first.
If you guys don't know how to get here,
and you haven't seen the other videos,
what you're gonna do is safely flip your
turntable over.
Make sure you flip it over onto something
that it's not going to damage the tone on
the underneath.
I have a special table designed to do
this, but
you could use a really big fluffy pillow
and achieve the same safety.
What you're gonna do is unscrew,
the four feet on the bottom of the
And then, you're gonna remove the 20
screws that are on the rubber base.
You're gonna pull the rubber base off, and
you're going to let the wires guide
through the rubber base.
And you'll be underneath everything you
need to be underneath.
Now, the main difference between what the
instructions are gonna tell you, and
what I'm gonna show you.
Is that I don't actually re, fully remove
all of the components from the turntable.
I actually find it easier to just leave
them in.
That way you're not flipping the turntable
a bunch of times and
you don't have to worry about doing extra
[COUGH] So the first thing that we're
going to do on this pitch fader is there
are two screws, there's one here and on
the opposite side.
We're going to remove those two screws.
And on this side there's gonna be a ground
cable that's
attached [COUGH] to the bottom of the
So remove the actual the screw and just
leave the cable where it is.
You're gonna see it goes through a little
Just leave that there.
And what we're gonna do is we're gonna pry
off the pitch fader.
Now, the other side of your pitch fader,
the pitch slider.
The button is gonna fall of on the bottom,
so make sure you don't lose that.
But can see the rectangular LED right
So what we're gonna do is [COUGH] rest it
in place.
We're gonna take a soldering iron and a
solder removal tool.
And we're going to desolder these two
prongs right here
that are on the bottom side of the LED.
Now it's easiest to put a little bit of
solder on the end of your soldering iron
while it's heated up.
And that's just gonna melt any solder that
it comes in contact with.
A lot faster without you having to hold it
in place for too long.
What I'm gonna do is heat them up.
And this is pretty much a solder, sucker.
It's kinda like what you use to take
boogers out of a baby's nose,
if you guys remember that, you know, old
But you're pretty much just gonna hold it
squeezed and
then when the solder's melted.
Your going to suck up any of the solder
that was there, boom.
So I'm going to do both sides.
just try to get as much as you can out of
Don't leave your soldering iron on the
actual component for
too long, you don't want to melt
[SOUND] But there you go.
Pretty much just sucked up all the excess
Now what we can do is take a needle nose
We're gonna flip this piece over.
You can see the actual prongs of the old
If you grab it and you twist it just like
that, they'll pop right out.
Then you can move [COUGH] your LED and
manipulate it to get that one out of
Now, if you look right here, where I'm
you're gonna see a little symbol.
Right there.
Now, that symbol is letting you know which
way to put the LED in.
So if you take a look at your LEDs.
I'll try and get this LED as close as
You're going to notice that one side of
the LED is shorter then the other.
So, what you need to know when you put
these LEDs in.
Is that the short side of the LED
is always gonna face the direction that
the triangle is pointing.
So, if the symbol looks like this then the
short side of your LED is gonna be facing
the point of the triangle.
So what we're gonna do now is take a look
at the symbol
on the bottom of the pitch fader.
This one says that the short side of the
LED should be facing
the actual pitch slider.
So we're going to place the short side
through this hole right here.
And we're gonna guide it out the back
holes where we previously took the other
one out.
And then we're gonna kinda hold it in
place as we flip it over.
Now, when we flip it over you're gonna
notice that they're gonna be straight up,
but they're not gonna be stuck to
So what you wanna do is bend them on
either side so
that it can just kinda be held in place
until you solder it in.
Now what we're gonna do is just take a
little bit of solder,
and we're going to solder it right back
where it was.
Make sure you get nice solder connections,
make sure none of that solder is touching
each other.
So, you don't want the solder on the right
side to be in any way touching
the solder on the left side.
A good rule of thumb is [COUGH] when
you're done soldering or
whatever you can take a flathead and just
slide it between there.
And make sure nothing's touching.
So once you've done that, that's it.
You've already replaced the light in the
pitch fader so
all you wanna do is screw that back on.
So take the same screws that you took off.
This is the ground wire that was coming
out from the one side.
You just want to push the screw into the
hole and
then line it up before you screw it back
Place it in the hole.
Take a screwdriver.
And you can screw it back down.
Then take your other screw and
just tighten it like this.
There you go, that's how easy it was to do
the pitch fader.
Now we're gonna move on to the 33 and 44
we're looking at the bottom of the 33 and
44 lights.
Now this is gonna be your small tear shape
dropped LEDs.
The smaller ones.
You're only gonna need two.
What we're gonna do is, we're going to
remove the two
screws that are on the green part of the
circuit board.
Now once we've got those two screws out,
you'll be able to lift from here.
Move this out of the way and manipulate
this actual board from coming off, and
we're gonna be replacing these two light
bulbs here.
So what we're gonna do is the same way we
desolder the other two.
It's gonna be the ones with the yellow
So we're gonna desolder the two over here.
And then we're gonna desolder the two over
Now you're gonna notice as you are taking
these out that they have little bushings.
Safety bushings attached to the bottom of
the old LEDs.
You can take these off.
They have two little holes that they are
guided through.
Can take those off and set them to the
And use them again with the new ones.
Now that little symbol that we were
talking about, is right there.
And also right here.
So you're going to keep an eye out for
which way the triangle is facing, and
that's gonna show you which way the short
end of your LED should go.
So this one says that the short end should
be facing the outside of the turn table.
So what we're gonna do is guide those
through on the bottom.
We're gonna seat them all the way flush
with the bushing.
And we're gonna bend the prongs of the
LEDs so that we can solder them in place.
So I'm just gonna quickly do these two,
and then we'll be back.
All right you guys now that they're both
soldered in place,
what you gonna wanna do is take little
wire strippers or
cutter, dikes, and cut the excess metal on
the prongs.
So don't actually cut into the solder
joint, but
cut the extra that's hanging out from the
And make sure that you actually collect
the the clippings
that fall off so that they don't show
anything else out.
So once we do that, we're going to slide
these two tabs back in.
Push it down.
And we're going to only screw in this left
because what we're about to do next is the
There you go, 33 and 44 lights have now
been replaced and we're gonna move on.
Next step is the tower.
It's a little bit more complicated,
but what we're gonna do is in the same
spot as we were.
Remove the black screws.
[SOUND] That are on the outside of this
black plastic piece.
There's gonna be three of them.
So we're gonna take off one, two,
And three.
Then what we're gonna wanna do next is
take a very small flat head screwdriver.
And what we're gonna do is pry off
this horseshoe shaped ring from this white
This is the piece that holds your power
button down.
So we're going to take a very small flat
head and use it as leverage and
twist it this way so that it pops off.
But when it pops off, make sure your hand
is there, because these things have
a tendency to go flying across the room if
you're not paying attention.
So, there you go, got that off.
Set that somewhere safe.
The next thing we're going to do is pull
this white piece straight up.
Sometimes it's, you know, been there for a
long time so
you might wanna get that screwdriver
underneath and pry it up.
Now, there's gonna be a ball bearing right
So make sure you grab that and set it to
the side.
Should have some kind of gooey stuff on
That's just a, like a lubricant.
Grab that, set it to the side.
Now what you can do is pull this whole
piece out.
And what we wanna do is just kind of flip
it and leave it in place.
Now we're going to pull the power button
out, just pull it straight out.
Now as we look inside here you're gonna
notice that there's a little
piece of plastic here.
We can go ahead and use needle-nose.
Pull that piece of plastic out.
This was kind of to dim the lights that
were in there before.
But you want them to be very bright.
So, just pull this out and throw it away.
You can throw it in the garbage.
Next thing we're gonna do is we're gonna
take a small flathead screwdriver,
and we're going to come under this tower
piece here.
Now we're going to very slowly and lightly
pry it up from both sides.
Just don't use a lot of force on this cuz
actually glued this to the actual circuit
board that's on the inside.
So if you use too much force, you'll snap
the actual plastic.
But there you go.
We got this piece off and you can see the
little remnants of glue on the inside.
And what we're gonna do as this is the
power light board.
See there's four LEDs.
On the bottom, this little piece of
plastic here, this holds it in.
So what we're gonna do is get under the
plastic and
pry that little circuit board up.
So we're gonna pull it straight up.
Actually it helps if you come in from the
bottom here and loosen these wires.
These wires that go all the way around
these poles.
Take one side off.
Take the other side off.
And it will just give you a little bit of
slack so
that when you pull this up, you're not
stressing the wires.
So now we've got this little PCB board
isolated, and what
we're gonna do is the same desoldering
process we used for the other ones.
These four solder joints on this side and
the four on the outside.
We are gonna desolder all of those, pull
these lightbulbs off.
And you'll notice that they have almost
the same little bushings that the 33 and
44 lights had.
Some of these are gonna be different.
Some of them are going to be clear
These are brown plastic.
What we're gonna do is save those little
bushings so
that when we put the new LEDs in, it's the
proper amount of space.
I'm gonna go ahead and desolder all eight
of these, pull these lightbulbs out,
put the new ones in and solder them.
And what I'm gonna do is as I put the new
ones in, there's gonna be excess length of
wire, so while you put them in, just bend
it so that you can hold them all in place.
I recommend putting all the lights in,
bending them, then going back in and
soldering all eight at the same time, and
that'll be where we come in again.
But, these are gonna be the bigger,
teardrop shaped LEDs.
You should have eight of these in your
So, once again, desolder these eight, pull
the lightbulbs out, save the bushings,
put the new lights in, and bend the
prongs, and then solder all eight back in.
Just to show you, this is the same board
completely desoldered.
This is your new LED with the bushing on
it, and
you wanna take notice of which side is the
short side.
Now on the back side of this, you're gonna
have your four little triangle diagrams
telling you which way that they all need
to go.
Now there different on each side.
So pay attention to what you're doing.
And this side is saying that the short end
of the LED needs to be facing me.
So we're gonna go ahead and put it in.
And we're gonna bend
the actual prongs over the side like that
so it stays in place.
And we're gonna go ahead and do the other
Now you can see all eight of them soldered
in place.
And all we have to do is take our wire
cutters or
our dikes and cut all the extra arms off.
All the little arms cut off,
now I'm gonna show you the easiest way to
put it back on.
So what we're gonna do is leave all this
loose wire.
Gonna flip it around, and we're going to
let that little black plastic piece come
up between the wires, and
we're gonna put the whole thing back in
place from where we took it out, right?
Now we're going to guide our wires and put
them back exactly the way that they were.
[NOISE] This can get a little frustrating
if you don't have that much slack,
but it be good to go once you get it in.
There you go, the wires are routed the
same way they were before.
So now what we're gonna do is work in
reverse order.
I've already put the actual PCB board back
I slid this cover over it, if you wanna
make sure that the opening is facing
the right direction what you can do push
it down and kind of twist it.
And you'll will feel when it catches
because that glue was in it before.
So the glue is gonna hit the PCB board and
it'll stop facing the direction that it
needs to face.
Then you gonna take the power switch, push
it back through the hole and flip it over.
[SOUND] And what we're gonna do first is,
remember that ball bearing that we had
And you can kinda place that, carefully.
And if there's enough goo there, it'll
If not, you're gonna half to kinda play
with it,
until it sits where it needs to sit.
And then we're going to put this white
piece back on,
it lines up in a certain way with the
power switch.
So, it'll slide right down.
And you might have to move this little
lever out of the way,
that activates your power switch.
But you wanna slide it down right on top
the ball bearing that was in there before.
So boom, that's in.
Next thing you wanna do is while you hold
that in place,
take that little half horseshoe piece that
you had, and line that up.
Now the easiest way to get this back on,
is to take needle nose pliers, hang them
off the edge.
And clip.
There you go, now it's back on.
Now what you're gonna wanna do is just set
the whole thing back
in position, and we're gonna put those
four screws back in.
So remember there's three on the edges and
there's one for this middle hole.
There we go, all the screws back in.
Your 33 and 44 lights are done and you
power strobe lights are now upgraded.
Now we're gonna move on to the pop up
First thing we're gonna wanna do with
the pico clamp is remove the two screws on
the outside and
we're gonna wanna pull it up.
Now usually there's a little bit of tape
right here.
You can kinda just pull your way through
that or pull the tape off, it'll be fine.
Now, pull that out without ripping it out,
til you see your exposed orange and brown
First thing we're gonna wanna do, is take
a very,
very tiny Phillips head screwdriver.
Make sure you have the right screwdriver
for this screw, because if you strip this
screw out here on the base of the light,
it's really, really hard to get it out.
So use the right sized screwdriver that
you need to, and
that's a very, very tiny screw.
So when you set that to the side,
make sure you set it somewhere where
you're not gonna lose it.
Now this top part of the lamp pops right
out and you're gonna see the old
LED with a bushing that you're not gonna
need anymore.
So what we're gonna do is look at this
bottom part of the light and
what we need to do is clip off this black
cable and
this resistor without clipping the brown
cable, right?
So we're gonna take our wire cutters and
we're going to clip the resistor,
clip the black cable, and we can pull that
black cable out and
then we're gonna clip the other end of the
resistor that's attached at the same
place that the brown wire is, but make
sure you don't cut the brown wire.
So you can throw that old resister out and
then what we need to do
is come to the bottom of this orange cable
and kind of work your way up, and
feel where, and this splices and cut right
You'll be able to feel like an
indentation, and
you can pull whatever excess heat shield
was off on this orange wire.
Now we have both of the leads to this
light b bulb off,
so what we can do is pull the light right
Sometimes you're gonna have this little
gray protective
thing going over the wires.
If that thing's getting in your way, you
can clip it off, set it to the side, and
we're gonna pull out our old wires, so
this is the old bulb.
You can throw this in the garbage or keep
it if you want for sentimental value.
What we're going to do is take our new LED
bulb wires and
before we do anything, we're just going to
lightly bend the very tips of the wire.
We're going to bend them in like a L
And what we're gonna do is slide them in
the top of the hole for the new proper
length, and we're gonna catch them coming
out this bottom side right here.
So once you see them start to come out,
you might have to use needle pliers,
needle nose pliers to grab em, but once
you see them.
Start to pop out like this.
[NOISE] You can guide them all the way
And what we're gonna do is guide them
through until we
have the blue part of this tape right here
almost touching the base.
So this is, perfectly where it needs to
If you think that it's too short, you can
kinda line up the, the color.
And you can see the LED is exactly where
the opening is.
So, that's kind of perfect.
Next thing we need to do is strip these
two cables.
Now, I've got wire strippers, and I'm
going to be using the smallest hole.
On the top of the wire strippers.
And we're gonna do [COUGH] is strip about.
Sorry I'm losing my voice.
We're gonna strip about a quarter inch of
the black and the red cables.
So you're gonna have about a quarter inch
of the wiring exposed on both sides.
you go.
And what we're gonna do first is we're
going to solder the black
wire to the old [COUGH] Spot where the
other black wire was soldered.
So, we can go ahead and
tin this wire by putting a little bit of
solder on the end of it.
Turn my soldering iron back on.
Luckily mine heats up pretty quick.
And put a little bit of solder on the very
tip of this wire.
That's called tinning the wire,
and that's gonna help you place the wire
pretty easily.
So the next thing we're gonna do, I have
to switch hands here,
is solder that wire And
the exact same place that we took off the
other black cable,
so it's going to be opposite of where the
brown wire is, so
we can go ahead and melt a little bit of
solder that was there before and
solder the new wire straight on boom!
Alright now that cable, or that wire
sorry, is soldered on.
Give it a little pull check make sure it's
not gonna pop off there.
And what we're gonna do next is we're
going to
strip about a quarter inch off of this
orange cable,
or orange wire here [SOUND]
Now what we're going to do is take one of
those pieces of heat shrink,
slide it over the side, and leave it
All right, now we're gonna take one of the
little resistors that came in our kit
and we're going to wrap one side around
the pole.
No, I'm sorry, we're gonna wrap one side
around the wire by just twisting it on.
And just twist it as tightly and as many
times as you can.
And try to make sure that when you're
done, there's not a real, real, like-
There's not a part that's poking out too
much coz what we're gonna do.
Is we're going to flip this back like this
so that we can slide the heat shrink over
And what you don't want is for any of that
to poke through the heat shrink.
So if it's not The heat shrink isn't
sliding over real well.
What you can do is just kind of squeeze it
with your needle nose pliers and
make sure that it's [NOISE] as tight as
can be.
There you go.
The heat shrink will slide right over.
But we're not going to slide it all the
way over,
we're going to leave this wire exposed.
And we're going to take our red lead and
twist it around the other side of the
So we're going to do the same thing,
twist it as tight as we can as many
times as we can [NOISE] Whoops,
tight as we can, many times as we can.
What we're gonna do is bend it this way.
And now our heat shrink will be able to
slide all the way over.
Everything that we just did.
You wanna make sure that there's no
exposed metal
on either side of this red and orange
Coz if that touches the ground or, I'm
if that touches any part of this metal
chassis, it'll short out,
it'll burn out your light bulb, maybe burn
out some other components.
Now once this heat shrink is over the
wire, what you can do is use a heat
gun but I was in the military so I don't,
you know, we don't do things that way.
We're just gonna use a lighter to
heat up the heat shrink and you're gonna
see that it shrinks.
You wanna use the hottest part of the
Let that shrink down and then just let it
cool off, blow on it.
Don't touch it cause it's gonna burn you
unless you use the heat gun,
in which case, you know, you should be
okay, but that's that.
Now we're going to throw away the pieces
that we don't need.
You'll see, once it's nice and cooled off,
just double check everything.
It's connected the way it's supposed to be
and what we're gonna do is put on the top
casing of our light, so you're gonna line
that screw hole up.
And you're gonna take that very tiny screw
that we set to the side earlier,
put it back in.
So I'm gonna use, once again, the right
size screwdriver for the job.
Screw it back in, and you want this to be
snug but you don't wanna overtorque it.
So make sure that once you feel it stop,
don't fight it too much,
just give it a gentle twist and it'll go
back into place.
You want to make sure that it can slide
down, and pop back up all right?
It's not loose, it's gonna stay there, so
don't over tighten it, cause you'll,
you know, torque out the screw and then
it's gonna be hard to get out.
So now what we're gonna do is just put
this piece back on.
Make sure that you're wires don't get
caught on the bottom, here.
Cuz you don't want to screw anything down
on top of
wires cuz what you'll do is you'll cut
through the shielding of the wire and
then you'll give that wire a ground and
you don't want anything to short out.
So just kinda move the wires out of the
Put your screws back on tighten those
screws, and that's it.
You should be done.
Everything from here is going in reverse
What you're gonna do is put the black
rubber base back on top of the turntable.
And you're gonna guide your RCA cables
through, as well as your power wires.
And when you're putting that down you
wanna make sure that you don't
put that down on top of any wires that
might have been sticking out of the side.
So you can see I've kind of tucked them in
place here.
They're not going anywhere, they're not
gonna move.
Just make sure that your wires are out of
the way, so when you put the rubber base
back down, you're not tightening it on top
of anything.
Put the rubber base back down, put your 20
screws back in,
put your rubber feet back on, flip your
turntable back over, turn it on.
Check your new lights out, all right.
