Blown power transistors - 2

It’s a process somewhat akin to pulling teeth. The giant heatsink they were attached to is out and cleaned of old, dried out heatsink compound. The two shorting transistors on the left are out. The two black transistors standing on the right seem to be OK, so I have left them. I may replace them later once I know the amplifier is operational again. Likewise the big black power capacitors that are probably suspect, but not apparently blown. New transistors in next, then back together for a first trial.
