Hello SB220/221  technicians (meaning knowledgeable technical amplifier diagnostician HAMS). I have SB 220 and SB221 amplifiers and have re-capped and worked on both several times. I have a problem in the plate current reading section and need to communicate via email with a knowledgeable SB 220/221 owner with service experience to help diagnose my problem.
Please drop me an email and we will kick the amplifier circuit around.
Thanks and 73, John, K5PGW
