Hey guys!
Looking for the last piece to my puzzle as both of my output cards have the same resistor(s) blown/missing.
These are pictured attached as R206, and R211.
The R206 resistor (although blown) reads 3.3k ohm on both cards although I dont trust it. And sadly R211 SMD resistor is missing. Does anyone have any insight as to what these should be? If im not mistaken they help set the output voltage and its the last piece to my puzzle of getting this amp back up and running from a blown power supply section, and quite a few blown output transistors. Im getting beautiful power supply and output operations on my scope, but dont want to install these cards until they are properly functioning 🙂. It looks as if all the transistors on the output cards survived from my testing.
I appreciate all and any help here!

The 3.3k resistors are OK. They are overheated but no blown, so its value surely is the proper you are measuring.
Regarding the 2 smd units, try to follow what are they doing: make at hand, this part if the circuit in a paper and send us it.
