Orange Amps Forum

So after bringing my amp to a buddies to jam i got home and no sound from dirty channel i tried tubes diff foot switch the switch on the front... I took it out of the shell and tapped on the tube sockets and tapped around with my plastic chop stick Nothing worked so i drove 2hrs to my tech and it was working when i got there and has been working since... He saw no issues but with out it malfunctioning its hard to diagnose i just dont need this happenimg at a show any ideas from you guys?

Low voltage situation can make the relay misbehave.

Like what could a bad reverb transformer cause low voltage? I happened for a week straght reassembled the amp tested it still nothing brought it to my tech and was working when it got there.... Im clueless what would cause this for a week straight then boom...
