This is my first posting on this board.
Anyhow, my amp went really quiet the other day. I usually play the clean channel, and rarely above 2 on the input volume.
I have to crank it up to 9 to hear anything, it's acting like it has a built in attenuator.
If I run a guitar cable between the send and return jacks... no change at all.
If I plug my guitar straight into the return jack, I get no sound.
Swapped all preamp tubes one at a time.. no change.
Tried different EL 34s..no change.
Cleaned all the various jacks.. cleaned the graphic sliders...no change.
