We know you get more power, but the issue is that there is a very real danger of encroaching on the output devices SOA. For any given load the danger becomes worse at higher operating voltages as you move up the SOA curve, even if you only let it play to the same power.

Yes father....

Sorry if I came across the wrong way writing that. I knew you probably knew that, I was just saying it for the wider benefit

It's ok Richie... you caught me before my morning cup of Chai.

PS: The anticipation of a comment like yours was the reason I put in the disclaimer "assuming the amp survives"

re circuit description in post 9; have you got CRC-CRC? i.e.30,800u- 1r0- 40,000u- 600u-1r0-1,000u. please clarify.
If I read correctly the final 1r0 before the small (2x500u) caps will cause significant signal induced ripple in the dc supply. Not good. Try moving the last 1r0 to between the rectifiers and first caps.

Remember, if you measured the 80V with no load, that will drop when loaded down. Depending on how quickly and how much it loads, you might be alright even at high power levels, since by the time you're drawing current and heating the device, the PS voltage might be back below 75V.
