Ok, figured I would try and pull the pre-amp tubes and see what would happen. I used a donor out of my Super Champ and did some swapping around.

The good news is that it isn't the tubes. Bad news is that I don't know what it is. I do know that everything, including the Super Champ is working now.

I think something must have come loose while I had her cranked and OD'ed.

Either way, for now anyway, both amps are running and sounding like a dream.

Thanks to all who have been doing some thinking on this for me.

Chris.
