So, 3200V across the stators. But they are not like conventional ESLs in that the diaphragm does not carry a charge; the diaphragm is low impedance (coated with aluminum)and driven, I think, along with the stators. Why this works, I have to sit down and re-think every time. However, because of the lack of high tension on the diaphragm, in fact the panels have lasted for 30 years, by and large. It's the amplifiers that cause problems. I am endlessly thankful for the help of "Steve O", an inmate on TubesDIY, who is also an EE and an owner of Bevs. Steve held my hand long distance as I solved a vexing problem with one of my amplifiers, which after all was done turned out to be a bad solder joint on one capacitor in the output circuit. After a while, I figured out it HAD to be something stupid like that, because I had been through and rebuilt the entire circuit, pretty much, and the amp was still oscillating.
