The IRFZ48 should work but it has slightly more gate capacitance so you may need to change the gate resistors if they're 100 ohms or higher. The Z48 is also rated for less current. If this is for a paying customer, you should use the original parts.

its 1 of my own amps i bought from a guy for $10.00 it was blown


If i use the irfz48's what do i need to use for the gate resistors they are using 56 ohm surface mount they say 560 on them so guessing it 56 ohm

The 56 ohm resistors are sufficient if they're within tolerance.

I guess ill have to order some 56 ohm resistors cause all i have right now is 10 ohm and the resistors that are in the amp are blown in half

Perry, do you need pics of a GT-24? I have to work on one tomorrow. I did take pictures of the Memphis 500.

back to this amp im thinking of using the irfz44's for the fets instead of the 75333p and switching the gate resistors from 56 ohms to 47 ohms wondering if this will work

The Z44s are rated for less current so the amp may not be as reliable. Either the 56 or the 47 ohm resistors will work.
