Sort of a funny story. I found a 1981 Super Reverb on Craigslist for around 350. Ad said that it had a slight hum and would need to be checked out - sold as is. I totally understood what I was getting into. I have some experience with electronics and feel pretty confident with recapping, replacing, and full-on revamping. I played through the amp - all seemed well. I take it home and within a few days, the vibrato channel goes out - super low volume. So, I open up the amp and discover that it's not a Super Reverb at all. It's a Pro Reverb (stamp on the side) Ultralinear. I'm now researching for a layout that will allow me to find out which caps I'll need, as well as other items that may or may not need to be replaced. If anyone happens to know of where to obtain the layout for this amp, it would be greatly appreciated. I thought it was the AA165 version, although this amp has a mid knob on both channels along with a push/pull master volume.
