Hello,
My Solo Head 50 amp has very low output, specially in Lead channel. Tubes are OK, and already tried swapping them. The overall output is very weak considering it is a 50W amp! Bias is OK (around 20mA) and already tried checking plate and cathode resistors. I am going out of ideas!
Also, the rythm gain pot is acting very weird. I replaced it (twice) with brand new pots, but the response range is acting crazy. For example, the pot around 15% provides the max loudness, and then fades out as you turn the knob upwards. The pot is OK since I tried 2 new ones, and has the same issue. It must be something ahead in the circuit.
Do you have any idea?
