so I can use the IRF3205 FETs as a viable replacement along with 47ohm gate resistors and the drivers as BD139 and BD140. When I switch out the drivers, where do each of the drivers go? such as BD139 to Q7 or Q8? BD140 to Q7A or Q8A?
The BD 140s go in the locations where you read 0 ohms between the center leg and the ground terminal of the amp.
I'd strongly suggest replacing ALL power supply FETs (12 FETs).

Okay so this is to follow up on everything. I just got a new dmm in and did testing to the rest of the power supply FETs and all of them tested as 0 ohms or about .5ohms then floating to another number. The resistors all had a weird number such as 23 ohms and only two of them read as 46 and 47 ohms.
I did testing to all of the output FETs and they all read the same which was about 33.1-33.4 ohms. I guess those are fine?
I ordered all of the replacement power supply FETs as Perry recommended and the drivers as well. I will update as soon as I get them in.
Thanks for all of the help!

Without knowing precisely where the probes were placed, it would be difficult to determine what they mean.
