Can I increase the rail voltage of the Anthony holton amp to 85 volts without any problems?

Look what I found.....
Look what I found in another thread:

G'day
The n-channel design should have no trouble handling supply rails as high as +-95 volts. The only thing that needs to be checked is the thermal stability of the o/p stage and perhaps a small heatsink on the pre-regulator ccT for the bias control...
The other thing would be the use of more powerful devices if 4 Ohm loads are to be used at higher power levels around 300 watts or higher...
Advanced Power Technology or APT make most excellent devices with case power dissapation as high as 500 watts..

I think he means Q11.
BTW: This looks like a really nice amp, I would like build one myself.

Hi everyone. First post here...
I also was intrigued by this particular Mosfet amp. A while back I did a quasi-comp. N-FET amp using some IRFP-254's I had lying around, but elected to use a PNP stage on the low-side FETs, as per "standard" quasi design. Does anyone have any comments on the use of a phase-spltter as shown in Anthony's circuit?
