I'm working on one of these and have a few question.
The board has several mods or maybe they were factory after thoughts. R137 and R108 have aluminum electrolytics caps in series - decoupling? Also what is the purpose of all the inverters on the input of the reverb pan?
Anyone have a picture of a chassis they can send?
I believe Loudthud had written a brief explaination about the differences between the beta and alpha preamp designs but I can't find it.
The amp has the original driver but the VC is rubbing - going to drop in one of these http://www.parts-express.com/pe/show...number=299-407
