UPDATE: I tried to switch tubes from EL34 to 6550 (This amp takes both). Now this time the fuse blew immediately the second I turned the amp on... Clearly a bad tube would not do that. As for the household power, I checked it and it actually seems pretty steady at 118/121. A. Durieux

By blowing I mean they go dead & fuse go as well. Only once one of them started glowing to red before going though... Just happens out of the blue once in a while, but VERY frequently. And with BOTH amps, which makes me think it's a power issue... Unles I am REALLY unlucky and got 2 amps with something like a trans problem. AD

Hi Need serious help here. I love tube sound but ready to switch to Solid State if I can't figure this one out!! Bought a Jolida 502 modified by Response Audio a couple years ago. From the start it started blowing tubes far too frequently (about once every couple months at least) After a while I finally had Response Audio replace it, and they kindly sent a new Bella Extreme Signature 3205i (A modified Jolida 302) This one blew fuse/tube after 30 minutes of play the first time I used it... I am living in a quite old building and wondering if the household power (spikes of high voltage) could be causing those problems. I do have a Tripp-Lite (which I understand is supposed to regulate those power spikes) but that's obviously not helping... Anyone has any idea/suggestion?? A. Durieux
