Behringer inuke NU4-6000 doesnt power on

[sazistas]

Hi guys, my amp suddenly stopped working while I had a rehearsal with my band. I heard a pop noise and it turned off. I opened the case and nothing seems fried. Is there any fuse on this amp? I cant find any. The amp doesn't have any warranty left also.

There's a breaker on the back. Does the mains cable check okay? Tried it with something else? You might have blown a fuse or something further up the line.

There was a batch of bad diodes that found their way into the power supplies of early versions,and the failure modes sound much like what you experienced. Have a tech check it out, from what I gather it's not a hard fix but it's not an end user fix either.

IIRC it was the NU6000s (not the 4-channel versions) that got those. Symptoms were that it'd boot as far as the red lights, but wouldn't switch to orange.

Those same diodes also found their way into some Crown amp around the same time so I'm not sure they can be nailed down to 1 specific model from any manufacturer.
