[Also cross-posted in the 50 MHz and up forum, in case one of the VHF guys has one] I have a Ramsey PA-20 220 MHz amplifier. Seems okay from what I can tell. But I can't find a manual for it anywhere. Closest I came was a similar Ramsey manual for a PA1 2m amplifier. Mostly I'm looking for the schematic and the instructions how to convert this from a Class C to a Class B--that's what the 2m manual shows. This one might already be converted, but I'd like to check it step by step. Anyone have a manual or know where I can get one?
