SORRY for my miss-calculation > mistake 😕 I'm irresponsibly going to blame Jack Daniels.
You may notice > that although I made a mistake of 50%, my total power amount does basically allow for TWO channels of aprox. 220 watts
as I stated in post #13.
Thank you for the encouragement 🙂
OK, I accept the apology. I misunderstood that there will be a transformer at the output. You want a transformer that drives the output stage, that's mostly unknown to me. I've built a lot of amps and other stuff, but never anything like this.
With that 600VA transformer and those voltages -+49V, you have a few options. Single ended AB class stereo 100+100W/8ohm (150+150W/4ohm), in bridge mode mono 300W/8ohm or to go for some D class. The mains transformer should be 1,5x - 2x as powerful as the class AB amplifier. Bigger is better. You can put a smaller transformer and it will work, but trust me, a bigger one gives a better sound. The degree of usefulness of AB class is about 60% and D class about 90%. The power is considered at 4 ohms because there are many speakers whose impedance drops below 4 ohms.
I currently have two DIY amplifiers, a 120+120W/4ohm mains transformer 400VA, and a 220+220W/4ohm mains transformer 800VA.

On the website of your countryman Rod Elliott, you have a lot of things nicely explained, with measurements and diagrams. There is a lot written about power supply.
INTERESTING > Thank you.
I guess I'm probably looking at something more like 200 watts with only ONE channel driven.
HIGH POWER is not actually my primary goal of this 'rather strange amplifier idea', but more to keep low power clipping away.
My anticipated rail voltages should still allow for rather high 'DYNAMIC POWER'. [ not continuous power ]

I use PSUD2 to simulate the power supply. It has performed well so far.
