I had the same problem with a Cary V12R amp. One tube did have a short and 2 more read replace on a tube tester. I now have a new set and no problems. One thing I used to do was to take out the fuse that was blowing before turning on the amp and put it back in, then turn the amp on, and the fuse worked fine. Hope it works for you, but I'd have those tubes tested on a tester. Also check the bias on your amp if it is not automatically adjusted. Good luck.
Jadis DA30: fuse keeps blowing
Since 8 months I own a 2nd hand Jadis integrated class A tube amplifier. It has worked fine until recently, when the left channel stopped playing, some 60 seconds after power-up. I opened the case, checked for any blown/ destroyed/ burned component, but the only thing blown was the left channel fuse. This I replaced and all was well again. Unfortunately, a few days later the left channel fuse blew again, within 60 seconds after power-up...
I have switched all the tube pairs (left pair to right and vice versa), but the left channel fuse keeps blowing, ruling out a faulty tube. Please note that after replacing the fuse, the amp is playing fine, but after some on/off cycles the fuse pops within a minute after power-up.
Has anyone experienced a similarly vague problem with a (Jadis) tube amp? What could be causing this?
Thanks for your assistance! Bernhard
