Looks good.

a question:

I looks like your screws are mounted on the PCB? Are the screw holes not big enough so that you can mount the VAS transistors on the heatsink with a good tension?

a suggestion:

Add two GND blade connector so that speaker GND cable can get its own blade connector.

I suppose it was just the time to weld them in place.

These screws with nuts are just temporary solution to hold firmly transistors against the PCB in the phase of soldering. All three transistors will be fixed to the main heatsink into its M3 threaded holes by M3x16 srews. Will post the pics to clear out that when heatsink arrives.

Nope, the way it is, it is the best - one GND connection point. There(fore) will be only one 6,3 mm GND faston connector circuiting three 1,5 mm2 wires: (+)GND, (-) SPK and (-) GND.

No way, it cannot happen. PCB will be in a vertical position, 5 mm distance between PCB and heatsink, ALF on big heatsink going max to 60°C.
