The IRFZ44 will serve as a good substitute.

There are no large 2 ohm resistors in the output section, as far as I know. Are you sure you're not referring to the 0.1 ohm or 10 ohm resistors?

If one is missing, you'd have to replace it. Did it break off of the board or was it desoldered?

Hmm I though that transistor would work just in case it failed.

Oh my mistake it's the rather larger resistors in the output section. I believe it was soldered off but I got it off another scrapped punch amp that I had and it performs great now. Also are LM137T Voltage regulators?
