I do not understand, is it your design/upgrade or APEX´s?

And would you mind to post a schematic?

For what I see, if it is a class AB I see it hard to reach such power with the drawn Toshibas, given their less than excellent SOA.
Then , if it a class H/G like the 900, then OK, it might work.

5 pairs 2SC5200/2SA1943 for 800W/4R?
Over transistors's SOAR.

Maybe ON-Semi better, like MJL21xxx series.

I saw this from Apex:

"I suggest to build SR200 sound is better, SR800 is only powerfull for PA use, and I will not share pcb or schematic for this amp.
Regards"
