Repairing a vintage solid-state guitar amplifier
Yes, there is a "DC Balance" preset and a "Bias" preset.
Oh, it all sounds too hard. Plan B beckons.
If you do carry on make sure you check the bias pot for
dead spots. If they go O/C they effectively switch the
OP transistors hard on - BANG!
You are either a brave man or an idiot trying to repair it!
