Record Player no sound

Hi,

I inherited my grandfather's old record player... looks about 70s or
60s (age).

It seems to run perfectly, other than the fact that no sound comes out
of the RCA-type output.

When i opened the unit, i noticed that one of the wires leading to the
output RCA jacks seems to be disintegrating. Any thoughts on the best
way to repair this?

-perhaps i should test the integrity of the wires? i've seen this
done, but don't know what tool to use;
-and replacing wires in this fashion?

....i am VERY good with computers, but absolutely clueless with
electronics (wiress, soldering, etc)...but willing to learn!

ANY SUGGESTIONS WELCOME.

Soldering, Resoldering and unsoldering are the Foundation skills of a good
Service Tech.
I learned by grabbing TV Chassis from The Dumpsters in the Apartment Complex
Nearby the Home where I grew Up.

Went to Radio Shack, bought a Cheapie Soldering Iron for like $10 and needle
nose for like $5 - and proceeded to spend night and Day Desoldering every
component I could see in sight. After Many burnt Fingers and blisters, I got
quite good at it.

Hi,

....that was exactly the reply i was hoping for... i think i will do
exactly as you've mentioned here! sounds like fun...

my next question is on checking the integrity of existing wires, (for
power?) and then selecting the correct wire to replace (i'm quite sure
that one of the two wires leading to the RCA output on this record
player are disintegrated, but i want to test the other one).

...So, here are my two questions:

-how do i check the integrity of a wire (this is a really basic
question, i know... but i know there's a device for this, but not sure
what it's called, what to get, etc.)

-how do i determine what kind of wire i should replace with? could i
simply remove the disintegrated wire, and bring it to radio shack??

yikes! i'm out of my 'element'... <lol>

Since this is an old record player, I wouldn't worry too much about testing
the integrity of the wires (although you could do that with an ohmmeter,
which is one of the functions of a multimeter). Just grab some speaker wire
and replace the old wires with that. Should do the job nicely. I'm assuming
that the wires you refer to got to the RCA jacks that are to be connected to
a speaker.

-how do i check the integrity of a wire (this is a really basic
question, i know... but i know there's a device for this, but not sure

Battery + light bulb (or buzzer). Use the wire you want to test as
part of the circuit (you don't need to remove it, use clips or hold
probes [wires] to either end). Put it in a case and sell it at Radio
Shack and you can call it a "continuity tester". If you have a
multimeter then it might have a continuity test function, put one
probe at each end of the wire and if it buzzes it's OK. If you have a
multimeter but it doesn't have a continuity test function then you can
measure the resistance of the wire. It should be a tiny fraction of an
ohm, if measurable at all. If you want to get more advanced then
wiggle the wire while you test it Actually, wiggle it anyway, it
may have an intermittent contact.

There are more advanced techniques, but for you to learn them for this
job would be harder than just replacing the wire (and likely
unnecessary). You'd also need equipment which I'm guessing you don't
have.

-how do i determine what kind of wire i should replace with? could i
simply remove the disintegrated wire, and bring it to radio shack??

You don't need to match replacement wires in the same way you would
have to match, say, a replacement transistor (in this application
anyway). Something equally as fat as the one you're replacing will be
fine.

yikes! i'm out of my 'element'... <lol

If you want to make a habit of this kind of thing get a multimeter (if
you don't have one already) Ł20 ($30) should get you a serviceable
one, though you could pick one up for Ł3 ($5). If you get serious
you'll want an oscilloscope. A really awful analogy from one software
guy to another: multimeters are the printf debugging of electronics,
oscilloscopes are the fully-fledged debugger.

Finally, and going even further off-topic from repair, if you're into
software you might find microcontrollers (PICs are the most common for
hobby projects, do a search) fun to play with. Tiny computers for $5
each (flash ROM, RAM, I/O ports...). That's what I usually play with
when Lego Mindstorms becomes boring, it's nice to write assembly and
know *exactly* what's going on sometimes, instead of using some highly
abstracted API. All this proper electronics crap everyone talks about
is just a way of making the bits your software pumps out spin the
motor or light the light
