What's going on you guys?
Today we're gonna talk more about signal
Now if you're having signal issues and
you suspect that your RCA cable or tone
arm might be the problem.
Here's a good way to read
electrically from the tip of the tone arm
all the way the the end of your RCA's.
I'm going to show you how to do this what
you should expect.
Now what you're going to need is a little
multi meter with two leads.
This little multi meter I got at Radio
Shack for $10,
and this multimeter has different settings
What you're looking for is an ohmmeter, or
So what you're gonna do is look for
the little symbol that looks like an
upside down horseshoe.
And you're gonna set it to the smallest
number setting that's available on it.
And it's gonna give you this.
It's gonna say overload.
Now what overload means that there's no
electricity passing between
these two ends.
And if we tap them together,
you're gonna get 0.0, or you'll see that,
something close to it,
which means that there's electricity
running all the way through the circle.
So, what we're gonna do is, I've made this
This represents the four prongs that are
inside the tip of the tone arm.
And we'll see if we can get a focus shot
of the tip of the tone arm.
But you can see that there's four prongs
in there and
this will be as you're looking at it.
So this diagram represents what each prong
So you're top right prong on the inside of
the tone arm.
It is going to be your right channel
So the way you want to read that is you
want to attach either one of these leads,
it doesn't matter which, to the right
prong inside the turntable.
And you don't have to worry about getting
anything electrical happening because
there's not chance of it.
So you're going to attach one end of the
prong to the right.
I'm sorry, you're gonna attach one end of
one lead of the multimeter to the right
and then you're gonna attach the other
lead of the multimeter to the actual
prong on the red RCA cable, which is the
RCA cable for your right channel.
So if you're holding one lead, only
touching the very prong,
the protruding prong of the red RCA cable,
take the other lead,
go inside the tip of the tone arm and
touch the top right.
You should get a reading with a very low
Anything less than ten is a good
between your prong, all the way through
the tone arm.
Through the circuit board, and to your RCA
So what you're gonna do is you're gonna
read out all four.
When you have the lead on the top right
prong, you're gonna stick the other lead
on the actual prong of the red RCA cable
which we already did.
And if you get a good reading which is
supposed to be a zero point something or
any low number that means that you have a
If it says this, overload or OL that means
that there's a broken connection between
the right prong and the RCA cable in which
case you might want to replace the RCA
cable or open up the tone arm compartment
and see if anything's disconnected.
So if it says overload is bad if it has
any kind of low number,
a number lower than ten, it's good.
Now what you want to do is that each time
you read one of these you want to connect
them and then maybe have a friend bend
your RCA cables all the way back.
And you wanna make sure that without
your number stays good the whole time.
Now if at any time, they're bending the
RCA cable and it goes into overload,
that means that there's probably a break
somewhere inside the RCA cable, right.
So that's when you'd look into replacing
So for the rest of these what you're gonna
We did right positive.
Now we're gonna do right negative which
means we're gonna attach one lead or
stick one lead on the prong.
Make sure when you're touching these
prongs that you're not touching
anything else inside the tone arm or it's
gonna mess up your reading.
So we're gonna stick one lead on the right
inside the tip of the tone arm.
And then we're going to read the outer
the outer metal exposure of the RCA, and
only touch the outer metal.
That's what goes to the right channel
ground or the right channel negative.
So without touching the actual protruding
we're just going to touch the encasing and
the right prong.
And that should read 0.0.
Or a low number less than ten.
If it reads overload, once again you have
a bad connection.
So we're gonna do the same process for all
Now when we do the left channel,
attach the prong to the left positive on
the inside of the tone arm and
then the prong of the white RCA cable,
which is your left channel RCA.
And then when we do left negative we're
the prong to left negative channel inside
the tip of the tone arm.
And we're gonna do the outer casing of the
RCA, which is your left ground.
So all four of these should read 0.0 or
a low number like a, ike a number less
Which will display that there's good
If you have overload at any point while
you're testing all these and
bending the cables, then you probably have
But I would make sure [COUGH] that your
hand didn't slip and
you didn't come off the prong or
Cuz that happens you might get overload
for like a split second.
That just means you might've moved.
So make sure that you're securely touching
both ends while you're bending these
cables so you can check and see whether or
not you need to either replace a tone arm,
replace the circuit board, reattach a
cable to the circuit board
inside the tone arm compartment, or
replace your RCA cables.
This is a good place to start.
Otherwise we'd be looking at different
solutions to signal problems
