Roger Modjeski and direct-drive ESL amplifier

So based on the discussion below, I emailed RM himself. He was kind enough to respond, twice. Seems he does/will make direct-drive amplifiers, and he inferred that it would be no problem to make one for the Sound Lab speakers, or any other ESL, I guess. He does not do mods to the Beveridge amplifiers at this time, however.

The URL for the vendor who sells his DD ESL amp is below.

I am not sure that 4000V is enough to get decent bass response from a Sound Lab speaker. Sound Lab uses a bass step-up transformer with a turns ratio of 1:200 or 1:250. However, I think RM meant to imply that he can fiddle with the voltage capability; I think.
