Too danger if run this circuit with 2SC5200/2SA1943 at max rail (95V).
Datasheet 2SC5200/2SA1943 show they're have 0.45A@100V@DC. +/-95 will get about 800 ~ 900W@4R, equal 15A current load. This impossible with 8 pairs power output transistors.
More than 15 pairs will to do it.

Maybe use ON Semi devices to do it. MJL21193/MJL21194.
1000W@2R equal 600W/4R, 350 ~ 400W/8R. The rail is about 85VDC.

this is a powerful amp. already checked with paudio sd18 inch speaker with folded horn bin.25ampere transformer and 85v dc supply .8 pair 2sc/2sa number trannies.
1500w can get with 25ampere transformer.
more rugged amp.
less heat.
