I just put new tubes and biased my old 115-65 and now I have an issue with the reverb that didn't exist before. When the reverb is switched on it squeals. The more reverb, the more it squeals. It also has a pronounced hum when the reverb is switched on and turned up above zero. This problem does not affect the tremolo circuit. Anyone have any ideas of what could be causing this?
