500w into 8 ohms load...

500W into 8r0 will need supply rails between +-100Vdc to +-110Vdc.
That 200V to 220V inside the amp is lethal if you make a mistake.

150V to 200V Capacitance is going to cost more than the rest of the amplifier.

How much may it cost? Maybe you should look for some used PA amp?

Isnt this the elektuur (dutch elektor) kilowatter from hmmmm about 15 years ago ?
When i saw the schematics Kapibara posted i think i seen this schematic .
My instinct tells me this was published early 90's (maybe late 80's)
Was a cool amp for those days (especialy combined with the elektuur preamp)
