Hi,
I have a dual-channel BA283 clone preamp.
One channel works well, but the other channel makes loud pops when switching the gain switch.
I swapped the boards with the 2N3055 transistor between the two channels, and the popping noise moved to the other channel (so it's not a dirty switch).
I measured the voltages on both channels, and everything seems identical.
What else can I do?
