In Reply to: RE: Amp turn off THUMP!!! posted by mgbpuff on December 01, 2016 at 08:22:35
I tried to find a schematic, didn't have any luck. If the cause is a power supply problem, like a double ended supply and the capacitors on one supply side discharges faster than the other, you would probably hear the thump out of more than one channel, so i'm guessing the problem is in that one channel. As a practical solution, due to weight and inconvenience, leave it powered on.
Depending on the circuit, there are a lot of pieces of equipment where turning it off and on is much harder on the equipment than leaving it on. I have a Sony surround sound receiver that has, other than during power outages, been left on for about 18 years now.

Thanks! I may just do that (leave it on). I'll disconnect the trigger. The amp works fine on all channels including the thumping left channel. If I continue allowing the thump/surge, I may eventually damage that speaker (it is a Sonus Faber Grand Piano Home tower).
IMO it's Broken somewhere! Get it Fixed.. is the simple answer.
No worth owning setup should do that. All Brochure babbles aside.
Either that or wait 'till it messes your speakers.
Then you get to fix Both.
When all else fails, call the manufacturer. :)
LOL :)
