Amp has a few issues with it .

First off the power supply fets are burnt .

The amp has 47 ohm gate resistors for the power supply fets .

The fets are marked CS50N

Anyone know what fets I can replace these with ?

CS50N06

They are equivalent to a Z44. That or better will work.

I’m assuming this IC controls the output stage .

Not sure if this ic is defective or not kinda leaning towards it being defective since I have a couple 22 ohm resistors burnt .

Is it marked with a part number?

 

[caraudioguy2100]

I will have to desolder it and check to see if it has a part number .

I believe it’s defective since the amp will power up for a second or 2 then go into protection

Here is a pic of the markings on the chip .

I can’t find anyone with stock right now
