Sundown Salt 12k

[caraudioguy2100]

This amp is using D600K and B631k as the power supply drivers for the fets .

Would the MJE171/181 and the MJE181/182 be good replacements for the drivers ?

Also every single power supply fets blew in this amp causing a lot of soot all over the board .

I know acetone and rubbing alcohol are known to clean this .

Can I also use a mild soap and water to clean the soot from the board and then make sure it’s 100% dry before replacing the parts and powering it up ?

The MJE transistors work as PS drivers.

Soap and water typically doesn't work very well but you can try it. If you wash the entire board, you'll need to use clean (no oil or water) compressed air to ensure that water under components is forced out.
