I moved several months ago. I was very careful in moving my Threshold 200.
Once hooked up it was dead. I called Jon he was extremely helpful, had me
remove the top panel, that exposed four fuses toward the back of the unit, one
obviously blown. I replaced it and the unit works fine. I would definitely call him,
he was spot on with what to try prior to shipping it to him for repair. Best of
luck, love these amps.
