So you think it is the power tubes? I guess it wouldn’t hurt to get some new ones and try it. Thanks

I got it about a year ago. I traded a guy for my Marshal DSL 40CR. He said it was not that old it has the 5881 jj power tubes and the ECC83S preamps all JJ. Serial number has a 04/20. Not sure if that means it was made in 2020?

Nothing changes when I tap with a wood dowel on power tubes

Actually new evidence. Both channels make sizzle noises when I strum the guitar at any volume past half way. Blue arc is faintly seen with lights off on the other power tube also.

The testng I have been doing is with nothing but a cab and one cord to a guitar. When i just let it idle with gain under 3 oclock the tubes just glow as nornal. But when I crank the gain the one tube makes that noise and has blue arc. It stops when I turn the gain back down past 3 oclock.

Thanks for replying. I have had a couple electronics classes years ago. I also was a an automation tech on automation machinery and robots. I have dealt with big 440 volt high amp things before so I know enough not to kill myself. But never was very good at trouble shooting amps. When I leave...

Have been playing it just fine and then one day turned it on and just no sound from speaker. I checked fuses. Swapped some tubes around. Re seated all tubes. Just guitar plugged straight in and MT 1 x12 cab with good speaker cable. Lead channel no noise, but a sizzle sound when gain is cranked...

So Brennen, did you ever get yours fixed. What was it. Thanks

I have this exact same problem just started one day when I turned it on and no sound. I checked everything as you did. I do not have a burnt resister. I checked cables swapped tubes. Tried everything. A sizzle sound from the OT maybe when I crank the gain on lead channel, or clean channel...
