Cold tubes!!

After over a week of not playing guitar while on vacation I turned on my Classic 30 with the Boss ME-50 and started playing. All of a sudden after a few minutes (5?) the volume just slowly disappeared. I took a look at the tubes and dared to touch them (I've been burned before!). The preamp tubes were warm, but the other tubes were not all that warm and those are the ones that I burned myself on before. I then took a look at the pedal to make sure everything was okay there and noticed that the cable from the pedal to the amp was coming out of the Line/Phones output. I switched that and tried again. Still nothing, and now the tubes were cold (except the preamp tubes still warmed up). So what might be the problem? I'm hoping that the fact the pedal went to the amp through the Line/Phones output didn't do the damage.
Thanks.
 
Do the power tubes light up in standby? If not, don't switch it out of standby. Just take it to a tech.
 
Your patch cable didn't cause your problem. If your not familiar with poking around in a tube amp,take it to a tech. It's probably something simple but there's lethal voltages inside.
 
Probably wasn't the pedal being in the wrong jack HOWEVER ..... if the pedal was switched on ..... then you would have had a direct short across the line/phones output. It's not impossible that could have damaged something.
 
I agree, check the fuse. Granted, the fuse probably comes into the circuit before the preamp section, so the entire amp shouldn't be functioning if it blew.

Well, there goes my suggestion. shit. I'd recommend taking it in - don't want to get yourself killed back there :eek:
