I had the same experience in my Rotel 2-channel amplifier. It blew some rail fuses and I had it in to ListenUp for repair. The service tech called me and said he went through and tightened down all the connections, replaced the fuses, etc.; said after a repair like this he doesn't see these amps again. Well it blew another rail fuse in about 5 weeks. I changed two things: replaced the quick-blows with slow-blows, per a Rotel document I found on the internet that listed recommended replacement fuses; and I stopped using the 12v trigger to turn the amp on and off. Its been running without problems since, which is about 8 months.
Preamp repeatedly blows fuses
I've got an Antique Sound USA PA-5 preamp from 1997 that keeps blowing fuses. I originally found the problem last night when I walked away from my chair and came back to find the preamp dead.
I immediately pulled the fuse and it was an "F3A250V" quick blow. I replaced it this afternoon and as soon as I turned on the preamp, it blew the new fuse. No fireworks, no pops, just a dead preamp.
I don't know where to go next, other than to call my local tube amp repair shop.
Any thoughts?
