My Fender DRRI, about six months old, bought new, suddenly started blowing fuses yesterday. It blew three fuses.
We had a heavy electrical storm that knocked out the power two days ago. It could have blown the fuse then but I noticed it yesterday. The power outage did not blow any fuses in the house or damage any other equipment.
I have been leaving the DRRI "on" in my studio a lot, for extended hours without switching to standby.
Could this indicate that the "rectifier tube" has gone bad? The rectifier keeps the current at a regulated, constant level doesn't it? This is the only idea I have.
Does anyone know which tube is the rectifier tube. There are three tubes at the very right of the cabinet looking at it from the back. Is sit the farthest to the side? Directly next to the side of the cabinet?
Would a visual check of the rectifier tube show any signs of it being bad?
When I put a new fuse in the amp the amp works fine and I can play for about four or five minutes before it blows.
Any ideas?
Yes it is still under warranty and will go in for repair if I can't locate a simple problem.
