Does anyone have additional information or experience with ESS (Electrostatic Sound Systems Inc in Sacramento CA) amplifiers? The company was apparently better known for their electrostatic speakers.
I just picked up an ESS "Model200" amp from someone local. He indicated it was from the late 70s and has a rating of 100W/ch (though he said it bench-tested closer to 125W/ch back then).
Anybody know anything about this amp?
