I'm a little bit familiar with the concept. And I mean a little
bit. My dad had a tv repair shop when I was "but a wee lad". I
don't remember much about those days, as I was a couple of years
old then. But, he still had his tube caddy, and associated tools
for working on all things electronic in the pre-solid state era.

OTOH if you're interested in 'playing' with the other parts it would
present a cheap learning tool.

I've already torn apart another receiver/stereo. It's the old
one from the office that quit working. When you power this one
up, the display shows an error message and then shuts down. I
took it apart to see if I could find some sort of fuse/circuit
breaker that needed to be reset/replaced, but couldn't see any
obvious problems, and didn't see any breakers or fuses/fusible
links that needed to be replaced. Given what a new basic
receiver goes for nowadays, I didn't think it would be worth it
to take this other one in and get it looked at. I may have it
checked out, anyway.

Some of the older electronics is worthwhile to play with if have some knowledge in the area. Ages ago I fixed Dad's tube-type "FM Radio" just
by following the instructions in the service manual. My old stereo
(used to supply background music while I'm on the computer) just needed
a power transformer to get it going again. Lasted another 10-15 years
before the power amp IC failed; determined it wasn't worth the work of adapting a replacement circuit (the direct replacement was no longer available).

Yeah: after a while I forget what I did and end up retesting/repeating.
Sometimes isn't a bad thing: discover you had forgotten to check a step
and find the problem.

Were you spying on me when I was working on the laptop
cannibalization project?? <G>

I'll neither confirm nor deny that question!

I have no idea why that would come to your mind! <g> The good news is I
did fix Dad's radio: worked for another year or so and then it started motorboating again ==> tube and/or other part went out of spec and could
hear a putt-putt-putt as something started oscillating. tweak and
twiddle: good for another year or so.

...This was also the stereo a filter cap failed and was dumping I don't
know how much voltage: wire-wound resistor about 2" long and the
diameter of a cigarette was glowinf red-hot! "You smell something
'warm'?" "Yeah -- I don't know what it is though". Happened to come
back into the room and have the angle just right and saw the resistor
glowing through the air slots in the cover. The unit was playing music
just fine!!

I don't really know. I just know it was odd to see one, since most
tube-based electronics had long been out of use (our organ at church
being an exception - it's a 1961 model Hammond ExtraVoice organ.)

Sure you don't. <G>

So when you folks talk about the warmth of the sound, is it from the
mechanics of the tubes or the filaments?!

works in stereo -- if it does the problem is at that switch, and the

I'd tried that as well. Of course, it's been quite a while ago. I'll
have to recheck it just to make sure what is well and truly
dead/non-working.

Hi Carroll!

OK. If by "helped a tiny bit" the speaker came to life, then you found
the problem in the switch. And admittedly replacing the switch

Actually, it helped "clean up" some of the noise I got when
adjusting the volume, now that I think about it. I don't think
it helped with the "channel problem".

The 'volume control' -- well, the original ones -- is a device with a
wire loop/spiral inside. Turning the control moves an arm which changes
the position of the contact arm over the spiral. When the arm is closer
to one end there is more resistance so less sound; at the opposite end
there is less resistance and more sound. Dust gets inside and causes an irregular contact. ..I'm not sure if oxidation plays a part.

sometimes means disassembly of the almost the entire unit -- at this age
I don't think it's worth it!

Nope!
