Esl Tube Amp

SillyCone · 24th April 2007, 09:51 PM

I'm planning to build a >500 Hz Esl Tube amp for my
treble esl:s, inspired by this speaker:

Anybody who knows were to find schemes or descriptions on a
good design?

Thanks, Jonas

Never tried it myself though, I'm more the solid-state-kind-of-guy

John broskie has suggested that a scaled-up version of his second electrostatic headphone amp would be a good ESL amp.

Not sure how much voltage you will need to swing for the mid/treble panel, perhaps 1000v? As drawn, that schematic will swing about 500v stator-stator.

I have heard it said that a panel over 2sq.feet in area, with a stator-diaphragm spacing of 1/16th inch,. and a bias of 1500v is good for down to 300Hz.
