Gave plate and chassis are excellent. Replaced on/off switch with new. These are super hard to get new.
Recapped with quality German Euro caps. Cleaned all switches and selector switches All small tubes are Telefunken with same date code GI. Power tubes are Fisher same date code DM. Bias resister changed 280 ohmes from 390 ohmes. In line with today's higher house voltage.
Easy bias and tube balance. No tools required except screw driving.
Amp sounds great and all functions work.
