You should know by now that photos are critically important since there are many similar amps. It may or may not help but it takes seconds to include and couldn't hurt to post.
If this is a ZED amp. I'd guess that the original components were a 0.1uF cap and a 2.7 ohm resistor. For the Zobel resistors, I've see some OEM resistors that didn't match the silkscreen.
Ok thank you for the info .
Next question is the guy said it melted his rca cables when he plugged them into the amp .
What do I need to measure or look for ?

Can I take a voltage reading off the shield ground of the rca jacks while twisting the transformer to see if I get any voltage on them ?
If so I place black probe on rca shield ground and where does the red probe go for a test point ?

I don't know what they're using for a drive circuit but unless they're using a lot of deadtime, I think you'll have to reduce the gate resistor value to something more common (47 ohms). If the drive circuit is weak (photos?), you may need to do more to use the 3205s.
Post a photo of the entire board and any audio driver board if 47 ohm gate resistors don't work.
Back to this amp .
The original power supply fets were BUZ102
Can I just replace them with the IRFZ44’s instead of the 3205’s and not have to change anything ?
Wondering if the Z44’s would be a better option
