CARELESSNESS

I'm curious. Is this actually true? I didn't think that a solid state amp that wasn't passing any signal would have a dead draw, but now I'm not so sure.
SS amp on, not being played? Yes. It will still draw a little bit out of the wall.
Big caps have some degree of leakage.
Transistor junctions aren't perfect insulators.
There is even some losses in the power supply transformer.
The resistance of the wire in the power cable will raw a bit of current while tha amp is on but at rest.
It's all pretty insignificant but does add up.
If it has a power light, even an L.E.D. boy, then it's really gonna stress that circuit breaker. :smug:
 
I was doing a little bit of practicing when I had to go take care of a problem. I left the music room and took care of the chore. I forgot I had left my amp on. It stayed on for 24 hrs. Before I remembered it. What kind of damage can I expect for being so careless?

Zero. I had a 1958 all tube Ampeg Reverbrocket I left on at school over Christmas Break around 1968, around 2 weeks. Was still working when last I powered it up in 2003.
 
Damage????
Less than zero, more than none.
I have personally installed power amps in industrial settings (such as machining centers, Mcintosh amps are famous for this) where they operate 24/7 for decades on end.
You have no worries.
None. :)
 
My first amp was/is (whatever) a peavey combo and got left on from the previous night until I got home from work (approx 18 hours). I had a mild panic attack and immediately hit the kill switch. Worried that it might be ruined, I flipped it on and tested it after about 15 minutes. As I feared, it blurted out some horrible distorted noises that faded to crackling and finally to near silence. The mother board was cooked and no tech was able or willing to fix it. Good news, amp repair shop contacts mfg and replaces combo with a fresh one.

So sleep well, I'm sure it'll be fine.

Seriously though, I think my case was an anomaly. If it was going to be a problem it probably would've shown up by now.

This is a historical moment. We have the first recorded case of a Peavey combo bass amp meeting an early demise.
