The ones I know that have made that at least sometimes are Cavalli and Woo and they have definitely more succes in that field than audiovalve.
Sorry - I misinterpreted the fact that according to Mr. Gilmore's plans some people are building ESL amps for other peope - hence "manufacturer". But one can not DIY ESL amps without the possibility to measure them - can one ?
I appreciate what Mr. Gilmore has done in ESL amp field. And other manufacturers implementing his ideas and improvements are certainly clever to do so.
However, Mr. Becker of audiovalve is not from yesterday either - I know of him for a hair below 30 years now.
Besides what became known as RKV and consequently RKV II, he did publish a DIY direct drive design with tubes in mid 80s. And if he, after trying any possible configuration to drive headphones, electrostatic included, came to the conclusion (amp with relatively high voltage + low step up ratio transformer ) is the best for powering ESLs all things considered, it only goes to confirm my idea from late 80s that never came to fruition due to myriad of reasons.
It is true that so far audiovalve has not been as successful in the field of ESL amps as Cavalli or Woo. However, it is Cavalli and Woo who are the new kids on the block - not the other way around. There is at least three decades
of experience behind the latest audiovalve creation - and even if it is not up to standard I expect from what I grew to associate Mr. Becker with, it is here - to stay.
I only wish the information on true capabilities was more complete and transparent - and that Mr. Becker would introduce his creation by himself.
