I've just rebuilt a threshold 400A that was blown in both channels. I used onsemi MJ121195/96.
All seems to have been successful (full power test pending) but I don't have a bias adjustment procedure for this one.
All emitter resistors were changed, as well as all electrolytics except the mains.

thanks! I figured it wouldnt be too hard to get an answer here partly since Nelson Pass himself is a member!
This amp is for a client but I'm looking foward to giving it a good listen. It will be up against my kenwood 700m on a pair of Radford S90 transmission line speakers

Pass always defers to the expertise of ZM.
Well let's see if your temperature calibration nomenclature
matches mine:
Blimey hot is 10 seconds hands on = 45 deg C.
Crikey hot is 5 seconds = 50 deg C.
Bloody hot is 2 seconds = 55 deg C.
X*?@! is 60 deg C.
All of these are within an acceptable range, although
X*?@! is resrved for the more mature constructor.

@ZM: Seen now this thread. Thanks for answers
