Just purchased a new amp a few weeks ago. I've used it for a couple rehearsals and mostly at home. Last night, I had a pretty frickin' loud jam session with some folks. I was running a 5.3 ohm cab and an 8 ohm cab. Total load about 3 ohms. The amp can handle down to 2 ohms. It's a solid state, class D amp. No tubes. This was definitely the hardest I've pushed this amp so far (high input gain, high master volume). There was a definite smell of burning electronics at some point, and it definitely seemed to be coming from my new amp. The amp itself wasn't even the slightest bit warm to the touch. I know it has a built-in protection circuit. It never tripped. Is this typical of a new amp?
