Default SE Tube amps with electrostats?

I have recently heard that single ended tube amps don't work very good with esl's. Is this true?

Hi,

I donīt see any reason why this should be so!
They are terribly inefficient, so Youīd be generating loads of heat and itīll be not easy to find good tubes, but apart from that, there should be not much of a prob.
Had one running (it was even a SE Triode) with the incredible KR845 running on 2kV plate voltage and it drove up to 1nF load without probs.

Thats what i figured but i thought i had better make sure before i ordered any parts to start building a 304tl SE.

thanks

I ran a pair of 811SET (IIRC) monoblocks on a set of double stacked Quad panels for awhile. About 20WPC. Plenty of power. But I don't think they liked the load much. Very bright and forward sounding. But waaaay better than the Quad 405 that was there before.

Ended up with 20WPC Class-A solid state.

All amps are different.

So are you planning on building an amp where you don't go to an 8 ohm apperant load between the amp and ESL? I'm starting to read on ESLs after making my first tube amp from scratch about a year ago. I want to run a low current, high voltage setup. Since tubes expect a roughly 5kOhm load, ESLs seem like a good match.

The idea of using a SET amp to drive an ESL baffles me as much as the guys who want to break an ESL up into 3 or 4 separate drivers and make a crossover to drive them. Why would you want to drive a speaker as nearly perfect as an ESL with a high distortion amp? What's the point of using an ESL?

Its because tube amplifiers produce light
