Default Optimus cat no. 12-1977

I'm ordering parts for a Rockford amp I want to fix. I've had this Optimus sitting in the garage for a few years. I may as well see if I can fix it. I've identified a bulging cap and burnt transistor. IRFZ44.
Question is, R130 is burnt up. I can't make out the color codes. It's right by the burnt transistor. Does anyone have that value and/or schematics for this amp?

Thanks Perry. I just found that googling. Unfortunately, R130 isn't listed. It's just a basic carbon film or ceramic looking resistor so I should be able to find something. There are other Z44's in there so I can probably just read one of it's corresponding resistors.
I'm not sure if I'd ever use this amp but, may as well try to fix it.
