I'm getting the impression, the tech I'm dealing with thinks I or my settings could be the cause, due to the fact I guess this is the second time within a year I've had this problem. I don't push the amp hard. It's in a 10 x10 room I converted to a studio for recording. Maybe you would be so kind as to help me again. My current settings for volume are:
Overdrive channel Gain is @ 2 Volume is at 75%. On the clean/crunch channel the gain is at 8 and the volume at 75%. The masters are both at about 2. This gives me a good tone at a low volume. In the small room, it's in turning the masters up even to just 5 would require ear protection.
The question is are theses settings pushing the power or preamp tubes to the point that would shorten their lifespan?
