Default Need help with Aleph-type CCS calcs

Good evening!

Im in a discussion at the Tube forum about Single Ended OTL (output transformerless amps), and a guy there came up with the (potentially very clever) idea of using an Aleph-type CCS as load in a beefed-up cathode follower output stage.
The Aleph CCS seems to be known for more or less doubling the efficiency in SE circuits, and efficiency is a major problem in OTL amps! (SoZ runs cool compared to an SE OTL!)

Ive decided to use 4 x 6C19 low impedance triodes per channel in a cathode follower topology with 400mA quiesent current, and now I need some help to fill in the resistor values in my little drawing below:


Any help would be appreciated!

Thanks,

Daniel
