Cheers Joe.
I know this thing's having a longer gestation period than a Blue whale but you know the issues I had previously and the ONE thing I really have to get right is the PSU as the circuit is pretty much sorted and refined to my satisfaction.
It certainly is totally silent in operation when I ran it up on load on a test bed. And no discernible temp rise. So it's all looking good. I reckon I may as well stick with plan A which is keep the reservoir at the original design 200uF followed by 100uF south of each choke. That will work and the amp will be stable at least as far as the power supply influences things.
