    Hey all, today my AMP stopped working, it wont switch from Red to Green, anyone have an idea of why that's happening?

    I opened an RMA with Monoprice, luckily me this thing has an insane warranty.

    The only easy thing to check is the tubes. If they are somehow loose or have a bad connection then the amp won’t come out of the start up. Otherwise RMA is your best option.

    Agreed , try a different tube. Assuming you did not try running single ended and balanced together which could take out one channel. The green - red is typically DC at the output , if the tube is not a dud then something else has happened to the circuit to overwhelm the servo and the dc protection circuit is doing its job.

    Thank you, I tried switching the tubes, I have a few here, I tried all of them in multiple different ways too, no dice.

    Well.. I opened a ticket with Monoprice, hopefully they can assist. I heard they are good about that kind of stuff.
