I've had my SVT 3 for approx 6 years from new. Never had any issues... Until recently!
Bit of background: I use a Rickenbacker 4003, through a Zoom B2 (just for a little distortion) and a SWR (4 ohm) 4 X10 Golliath cab. I have gain control set at about 2 O clock, (the clip light frequently lighting up) and use the master for overall volume (usually set at 12 O clock). I play in a loud Punk band. I am aware of the discussions around using the gain - not as a gain and it's ok to allow the clip light to come on etc, I've found this works fine and I love the sound I get... So recently the amp kept cutting out - still had power and gain light coming on but no output, it then jumps back to life a few seconds later (which at a gig feels like an eternity) I took it to a well reputed amp specialist, he serviced it and replaced the fan. He ran the amp for 24 hours and it never missed a beat! Thinking problem solved I gigged the amp....same thing happened again, I took it to a second well respected amp company and they ran it for 2 days... No problems found! I've changed all cables, bypassed the pedal nothing helps. At a recent gig it did the same! I then reduced the gain so the clip light hardly came on at all and reduced the master, my overall volume was lower... But the amp stayed on!! I'm a bit happier that I seem to have found the potential problem, but surely this isn't right?? Sorry for the long winded post, I'm really frustrated and hoped someone can shed some light. Many thanks
