Recently I bought a pair of audiostatic ESH100 to rebuild it completely. It's an hybrid electrostatic with a subwoofer in the base. I have no idea what to expect of this speaker in terms of sound quality. But because I just finished the repair of my Quad 2805 speakers (at least I hope so) and have a lot of stuff left in the esl repair kit that I bought from Australian based ErAudio I decided to buy a pair of worn out ESH100's.
While taking the speakers apart I noticed that there has been worked on before. The foils were in bad condition so I have to renew them. I have a few questions.
In the first picture you can see the resistors of the stator segmentation. Are these the correct resistors ? I have read that some people use a different segmentation. Is this recommended ?
In the second picture - the high voltage pcb - there is a fat green resistor that has a burn mark underneath. What is the cause of the overheating of this resistor ? Playing too loud?
In the third image a picture of the crossover. You can see a fat capacitor and a coil. The capacitor doesn't seem original to me. Could it be a (useful ??) mod.
In one of the threads I have read about incorporating a neon in the hv circuit to check for voltage leakage. Can someone tell me how ?
