I am looking for assistance for a Kicker 600.1, I hope PapaZ can assist with this.
When the amp is powered, the red lite is continually flashing. The output Mosfets IXTP56N15T is shorted. But there are many other defective components, Q17 D34,Zd8 and R142 and R143 (open) and I assume IRS20957s is defective.
I need to know what the value of ZD8.
I also found that a lot of these part are not easily located.
Any help is appreciated.

ZD8 is a 13v zener and Q17-BCP56 are the 12VE tied to R143,R142-10 ohm and Pin 11/IC4's VCC port. It appears that Q19-IXTP56N15T or D34-1N4148 failed and caused 12VE to short taken out everything in its path. I don't recall seeing this type of failure but replacing IC4-IRS20957 and Q19,20 along with the other parts should be the fix. I'm looking at a CXA600.1 schematic but for all intents and purposes is the same amp. I don't recall if the output mosfets where changed to IPP200N15 due to IXTQ sourcing or obsolescence, but the IPP should be drop in replacements.
