Many thanks Shinja! A quick search about Soya Susumu returned the "direct dynamic coupling". An explanation of this found here:3C24SE amp... post #33. Difficult to find anything else.

It's unfortunate that none of the articles by Soya Susumu is complete in the archive, there's always a page or two missing. Some of his designs are very similar to (perhaps even the same as) smoking-amp's Crazy Drive or Twin Drive, i.e., both the control and the screen grids of the output tube(s) are driven.

I recall I couldn't find precise calculations for the twin crazy drive. I guess I have to read again smoking-amp's thread. Thanks Jazbo8!
