Can you post more pic inside the amp in the left part of the amp?
The fact till now is the noise come from power since it is at 100hz. And it come after potentiometer, since the hum doesn't affect by vol control.
let try 2 more wires since they seems just stick to power....If no effect after this, I have no idea~
White arrows....they are after potentiometer, but the tube circuit seems after the potentometer as well....so my analysis about the problem on no effect of changing vol was not compeleted. The problem part should consider the whole part after potentimeter. This part is the tubes and cap.
