Last Saturday I powered on my amp (Quickrod) and let it warm up a bit. When I flipped the standby switch to “on” it blew a fuse. So I replaced the fuse and it happened again, this time I saw a bright flash coming from one of the power tubes. I emailed Scott and he said most likely was a power tube failure.
Before this amp I played a 2204 JCM for years. I have never blown a power tube like that. The Marshall always “told” me when they needed replacing. It would start making popping noises and minor volume fluctuations.
I reordered a set of tubes from Splawn and I also have a set of reissue Mullards on hand.
These tubes were what came from Splawn and have lasted almost 2 years. I posted about this on the Splawn board and Rhodes guys seem to think that the tube(s) died prematurely....
Ime, a set of tubes usually lasts about a year, maybe a little more with regular use.
Does anyone here think this is unusual?
Also, what is everyone’s experience with actually having a tube fail? When I visually inspected the tubes, I don’t see anything that looks abnormal....of course that doesn’t mean much.
Also, thoughts on a bad PI tube causing a blown fuse?
Thanks!!
