Dual Recto Solo Changed power tubes, NO channel 2 or 3?????

[Bryan]

OK. So a couple weeks ago I changed all my preamp tubes and the Rectifier tubes.

Today my power tubes finally arrive (backordered) and I put them in today.

I fire up the amp.

Channel 1 is fine.

But I get no sound from channel 2 or 3. I tried bypassing the footswitch, moved the knobs to manually select the channels.

Nothing.

What is going on?

Any and all help will be appreciated.

Did you put the old tubes back in?

Sounds like a preamp tube went bad one you, or something else got jolted (electrically or physically) when you put in the new power tubes.

I'll try swapping out pre tubes one at a time. I hope Mesa just sent a bum tube

And we have a winner!!

Pre amp tube number 3 was the culprit.

All is well. Thanks for your help guys!
