300W power amp with PSU

I finally learned to put transistors the correct way around in my class B amps. ;-J

Some of the components (decoupling and bias) in the intermediate stages may not be necessary. This is half-remembered stuff I fiddled with until it worked.

Better PSU for quicker startup and less ripple, but still suffers from both. Making the leftmost 1mΩ resistors 1Ω instead improves that ripple but greatly increases startup time.

Resistors added to monitor power voltage at the same time as current (1kΩ, 1mΩ), but they're not monitored at present.

@eekee, to simulate two different systems together in a !!transient simulation setup!! is a novel idea, but will not help you. Separate the PSU from Amplifier and test them separate.

Thank you hurz. I think I've learned a little from the combination, but yes, I found myself wishing I'd separated them. I don't plan to combine different systems often.

Looking at it again a month later, my overriding impression is "Oh that output is bent!"
