is blowing fuses. Possibly lightning-related, or possibly not, but I need to fix it. More details inside.
My fairly new Egnater Tweaker 40w head was accidentally left on in my outbuilding rehearsal room
during a thunderstorm. We had a lightning related power outage during it.
When power came back the amp was dead, although it was at least 24 hours before I noticed so it may be unrelated to the storm.
I tracked this down to a blown 3A fuse in the mains socket, which I replaced. I powered it back on with all the tubes out to rule out a dead tube, and the fuse instantly blew again.
I live a couple of hours from anyone I trust to service amps, which is also how far I am from an Egnater service dealer, so if I can solve this myself so much the better. I'm happy working on tube amps and I know how not to kill myself.
Presumably this has to be a problem in the power section. Any clues? There's a surge protection cap which looks fine but is my main suspect at this point.
