Here is the board only from the AS-1 filter. (Named the AS-1 for its designer Al Sekela) It is a passive parallel filter with four R-C-R circuits and a resistor/inductor string of four resistors and four inductors to ground. It uses WIMA MP-3 metalized paper safety caps, PRP resistors and Hammond inductors. I built them soldering point to point with WBT silver solder and then sent them to be Cryo'ed. The parts alone were about $45 each I think. This board only needs to be housed unless you like living on the wild side and then have a power cord (three conductor) connected to it. The three connection points will be marked. Again it is a parallel filter so it works on anything connected to the same outlet and circuit the filter is plugged in to. Nothing plugs into the filter therefore there is no current limit for any device it will serve. I also have gold and rhodium Furutech IEC outlets you can use with this project for $10 these were also cryo'ed.
