R51 and R52 are the same (22 ohms). Use flameproof resistors. Values taken from the board shown below.

I kmow I am new, but that is a 500d bord, there is only a 60 amp fused power supply. the other 1000mcd used 80amp. I would check that before replacing 4 irfz44n and 4 irf3205 trans, as the value may not be the same. If the sub is Ok, it is ussuualy the driver cicuit that burns up. you can allways call 1-800-467-2400,Fulmer Co. go to tech and just ask them if they can help you out, you could have been a long time customer and just need some help.
 
Just making sure that someone hasn't replaced the FETS with the wrong ones then had me fix it. and the resistors are toast. no way to measure or read. at r41-r44 but i can read r46-r48. there are 4 3205s with 23 ohm resistors and then there were 4 irfz44n's with burnt resistors.
 
The resistors sometimes fail when the capacitors or diodes that they're supplying power to fail.

If you can push down on the top of the cap and is goes down and pops back up, it's just the plastic cover that's bowed up.

If you have any other questions, start a new thread. I won't answer any other questions here.
