Yeah - the AstroSonic radio's do sound great - I used to have a Magnavox stereo console that had one. One channel was dead, but man, the other one sounded great (when you could get the controls set so they actually worked, they were pretty worn out). I ended up junking that console, it was in horrid shape - the amp sat around here forever and ended up getting tossed, I shoulda kept it for parts...
The sound does work on the TV, but all that means is that the tuner is getting proper power and is working - all the audio gets fed through the Hi-Fi amp. So maybe the B+ supply has a chance of working. I'll check it. Once I pull out the chassis, I should know more - I just haven't had a lot of time. Maybe tonight after work.
Thanks for the tip about the flyback voltage Chad - I'll try that one too. I certainally hope the flyback is good... I have no clue where I'd find another one.

Any value within 20% of the old value, and equal to higher voltage rating will be fine.

Brilliant! I was initially just thinking power supply caps - I've not seen this problem before, and I hadn't thought about that. I don't work on SS stuff all that often, and when I do, typically it's just _dead_ and has a power supply problem. When I start working on the amplifier, I'll start there. Thanks!
The changer should be easy. It's the same changer I've got in my Magnavox Concert Grand, and as such, I've saved them from every junked Magnavox anything I've found, and I have spare motors, idler wheels, and whole spare changers. Obviously, I'll try cleaning it first, but it's nice to know that I've got the right parts, just in case.
