Both Mr. Sulzer and Mr. Jung made those regulators known. As we speak we should not forget Mr. Didden who made pcb's for Mr. Jung's article.

A super regulator from 1977, Mr. Kaneda, Japan. Picture here

Anybody who have seen a super regulator before 1977?

If you use a LM317/337 these devices determines max current, 1-1,5 A but basicly the pass element set the max current.

Topology is the same, but some of the actual components differ from the circuit you posted, PerAnders.
A lot of the circuits of Akihito Kaneda were published in the editions of the L'audiophile magazine in those days.
L'Audiophile sold the pcb's of the Kaneda regulator.
I'll have to dig up the mag, its been over 20 years that i did Kaneda and Hiraga stuff, i should even have a L'audiophile parts catalogue from the early 80s somewhere.
