how to bias a Llano design CAS 300. I have 2 of them one of them is running at a toast 120 F while the other has been fixed and biased to cold.

Help is appreciated.

If you don't have the schematic check emitter resistor MV on cool amp (example: 22mv) , adjust bias on hot amp to match.
Also, let amps temperature stabilize for a while and recheck MV
