Hi every one, i have problem with lightning audio LA-1000MD, sound break while gain up, please help.
Is the problem with the gain control or is it with the level of the output?
Does the rail-rail output stop when the sound cuts out?

Break sound when the volume goes up a bit loud, especially when the bass gain is increased, rail to rail not cut off.
If you leave all gains full up and increase the input level until it cuts off, does it cut off at the same point (changing NOTHING on the amp, only changing the input level from the signal source)?
What's the DC voltage across the B+ and ground terminals of the amp when the amp cuts out?
