I try to specify transistors so that PSRR will be high up to the maximum current, I don't rate it just based on power dissipation limits.
BTW: Somehow I doubt this, but is it possible to run multipliers in parallel to increase current?

You could potentially use parallel slave transistors to do this but then you might start to overload Q1. The whole circuit needs to be reexamined.

Also, the ancient Jean Hiraga from 'Audiophile (a magazine in France) said that the Darlingnot couple used will easily be prone to very high frequency odscillations.

I think it's a Sziklai complementary pair. From my reading I remember several articles that say poorly engineered Sziklai pairs can be unstable, but with proper attention to detail it's not an issue.

If anyone using this gets a small sound that is sorta like electrical farting it seems that too much capacitance after it will cause that. Not sure how voltage used will determine the capacitance that is too much. At 50v 1800uf was too much along with the circuits 200-400uf~.

Keantoken. I can't remember whether you had any more of the KM boards for sale or whether you were going to run off some more. I'd take 4 if you were sending out for more boards. Thx!
