I let my amp warm up tonight and when I plugged my guitar in there was no sound. Checked all the cables, which were ok, but there was no sound coming out of the amp. I turned it off and waited 5 minutes. When I turned it on, the amp did not light up this time and I had blown a fuse. Should I just replace the fuse and see if it happens again, or is there something else I should be doing. Thanks for you help. John

Change the fuse, turn the amp on, leave the standby off. Look at the power tubes and see if one (or both) is glowing abnormally. Turn the standby on, look at the tubes again. If the tubes are glowing red or looks like fireworks went off inside one of them then turn the amp off and get a fresh set of KT66. Make sure you bias the amp with the new set, either yourself if you know how or take it to an amp tech.
Other then that it might be better to just take it to a tech in case there's something more then just output tubes.

Thanks, when the amp was on I checked the power tubes and they seemed lit up as they normally are. I will try your suggestion tonight. Just in case, can anyone recommend a good amp tech in Dallas. Thanks. John

Before taking it in, change your rectifier tube.

I blow fuses all the time on mine I think because of power surges in the house current. I have blown maybe 5 in the 2+ years that I have owned the amp all playing at really low volume at home sans Airbrake. I have never blown one playing at a club. Maybe it is my rectifier.
