This apparatus is to convert the low voltage high current of a typical audio power amplifier to the high voltage low current that a high quality electrostatic loud speaker requires. An all passive 1:50 transformer step up to match the impedance. Included in the center of the arrangement is the necessary High-Voltage Cockroft-Walton  polarizer that an electrostatic loud speaker requires for living-room sized listening at 1600 volts. 3D printed with ABS with AnTek toroidal transformer cores.
