OK. If by "helped a tiny bit" the speaker came to life, then you found

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".

Nope!

easy fix is to move the speaker leads to that set of outputs.
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.

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.

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.

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

There was a drug store in Jacksonville, Arkansas, that still had
a tube tester back in the early to mid '90s. Now, what a drug
store was doing with a tube checker, I don't remember, but they
had one. <G>

I have no idea why that would come to your mind! <g> The good news is I

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.)
breaker box for the building is, so it wouldn't be any trouble to
shut it off there, before changing a breaker somewhere else.
Just make sure you run your lights first -- gets dark with the power
off! <g>
Montgomery Ward Catalog is still going, plus somehow they affiliated
