Gentlemen,
Thank you so much for all the advice!
It's a Gold tuck n' roll, and I will definitely be putting a multimeter in various places on the unit to check it out.
If I isolate the power stage from the rest of the unit, what voltage am I substituting for the filter caps, and how can I tell if they are bad?
The guy who sold it to me lost the serial number plate, so I am unsure of the RV/PA designation. I really wish this forum allowed pics so I could show you the unit. It would really help to figure out what schematic I am supposed to be looking at from the site.
It was dropped at some point, as the transformer mounts are bent, and the reverb/ trem/vibe circuit board mounts are bent, and there are replacement transistors/ resistors/ capacitors over the four boards. There is a fair amount of gunge covering everything- I will have my hands full just cleaning it up.
As for the reverb tank, I've been researching on the net and I found the MOD 4FB3A1B. Someone was suggesting it as an alternate, as I've googled Accutronics 4FB2C1A, and come up with nothing. I like the concept of a longer decay reverb, but it's the A vs C in the connectors (grounded vs insulated on the input).
This is a learn as you go kind of thing- that's for sure!!! But I am excited to really get it running smoothly!

Cheers--Steve
