A friend is bringing over a sb220 amp. The problem with it is that when amp is keyed, the plate volts drop to almost zero. I am thinking the cap bank probably needs replaced. Anyone ever see this happen in an amp before?
I know the guy that runs this drake is a heavy hitter. Last year he went thru 3 sets of tubes. Why he runs it at a 1500W carrier is beyond me. I had to install a fan in power supply to keep it cool. Also he smokes, so everytime he brings it over I have to clean everything before I can work on it. Nasty.
