@russ69 I think I’d be all over Cary. HEY! Provide some service or provide the info I need to fix it myself. I’d get someone on the phone to tell me I’m SOL, then I would tell them, bad mistake, you guys are going to be my hobby, and it’s going to get ugly, your call.
They don’t troubleshoot over the phone any more. Been there done that with them and seemingly got the last lead designer-tech in trouble there helping me with my V12R mods. He quit two weeks later. Felt bad. He went on to new things, now designs and builds pro audio tube microphones. If lucky, will just tell you to send it in and charge for the repair. Double-bubble and double-box if you do.
Probably better off sending it to a good local tech, and many can do as good or better job. Avoids shipping cost or risk of transport damage. Have them replace the coupling caps and a few resistors with better ones while it’s there. That amp can sound a lot better with a few upgrades. Some techs like to throw in a Triode/Ultralinear switch too.
