One thing I noticed that didn't seem right was, a sizzling sound through the speakers when switching between standby and play. I wasn't sure if it were a problem or not....just assumed not. I just gave the SVT a good workout, and after about 20 minutes at gig (a LOUD gig) volume, I noticed after I'd suddenly stop playing, you'd hear that sizzling sound through the speaker for a brief moment. It was particularly worse on the lower, power draining notes versus the higher notes. Ignoring it and jamming on.....after a short bit, the volume would drop dramatically, and distort out into nothing but silence. A few seconds on standby then back on, and it would be fine. But only for about as long as you left it on standby before it would start to fizzle out again. This sounds like a problem with the caps not being able to keep up possibly? The caps are all new in it though. Help!
