FS/FT: Unfinished electrostatic speakers

Status

I have no use for a pair of unfinished and untested electrostatic speakers
that are maybe useful for qualified esl-freaks (must be certified technicans).
You must have galvanic isolating power transformers (with 2 different windings)
to safely use the stepup transformer boxes (for the diodes-capacitors cascade)
and a power amplifier to drive the internal signal transformers (I guess, I used 220V->9V
transformers with exchanged primary and secondary connecting for the signal transformation).
Bias can be adjusted, a fuse and a power control lamp are also installed.
The silver metal bows are for the diaphragm (haven't).
I don't guarantee for anything.
Shipping costs are about 50US$ (wordwide).
The parts are at least worth 50US$.
What I need is just DAC and CDP stuff or a SR-003 (even broken).
