Hi all enthusiasts and professionals! Looking who could help with schematics for this amp?? Had this big fella working without a glitch for couple years until last week... When power on, one of the outputs failed, protection circuit didn`t kick in when it suppose to, which caused to fail all outputs on that side + put pressure on power section and ALL power fets also failed. There were lots of smoke and was expecting worse picture, but seems not too bad of a psychical damage... Yes i know the bill will be high enough due to amount of fets, but want to see it going again. So looking who could help me with a schematics as some diodes needs identification, + all IC`s markings on the output driver board are brushed. Thanks in advance to anyone!
P.S maybe someone worked on those models before and knows how to improve protection circuit?

If you go over to the Car Audio Section of this website, there are a lot of reference's to this PCB.
Type in the DMV1416? (it will be written on the back) in the seach, in car audio

@Tom7227 there is no such thing written as DMV1416 on the back or front... anyways IC`s are sorted now by a mighty man Perry 🙂 next and i hope final dilemma is to identify diodes (see picture below), they are melted and i can`t identify them :/ somebody even said they might be zeners
An externally hosted image should be here but it was not working when we last tested it.

I think I have one of those amps in the shop now, those diodes are 9.1v and resistors are 510 ohm
yes resistors are 510 ohm, but they were all good. Soldered in 10v zenners. Was onto some other things lately so had no time to finish it up. Putting my hands on it again so will keep you posted
