CCD-2400 Concept Car Amp

[raljazz77]

Hello all,
1st time poster on this interesting forum.
I'm a tv repair tech (Boca Raton, Florida), and recently had someone bring me
a Concept Audio amp; the actual model number is no longer anywhere on unit, but noticed an earlier ad from [Mauquill], who had the exact same issue, which is there are 12 MOSFET (to-220) transistors dead shorted in this unit. Do not have the schematic, but proceeded to find all three 25A fuses were open, and with the before-mentioned shorted transistors. Performed resistance checks across all the output transistors and other solid-state devices including the caps, and found nothing else out of norm. Replaced the IRFZ44N transistors, with same value good transistors, and applied 12v to both 12 and REM, and transistors shorted ONCE again.
I would appreciate if anyone has the schematic/diagram, or at least confirm that these are the correct value transistors.
Thanks,
Ralf
