 +Mechanically, not much novel was done in the construction of this coil.  We used 26 AWG enameled magnet wire from McMaster, wound on 6" drain pipe from Lowe's, for the secondary.  The secondary was coated with between 10 and 15 coats of Minwax Fast-Drying Polyurethane, as is standard for many coilers.  The primary is composed of about 20 feet of 1/4"-diameter copper tubing on a conical form; it's held in place by six laser-cut acrylic supports.  (The supports also hold the secondary in place.)  The supports are solvent-welded to a polycarbonate base.  The whole primary support feels sturdy; the secondary sits in the middle, and can be removed for easy transport or maintenance.

 By December 27th, 2011, the PFC circuit had been built, but not tested.  First powerup happened around the first of the new year; the circuit was rebuilt in the new configuration on the third or fourth, and the bias supply was integrated on the 7th.  The PFC circuit is now operational, and has been tested up to a load of 85W or so. By December 27th, 2011, the PFC circuit had been built, but not tested.  First powerup happened around the first of the new year; the circuit was rebuilt in the new configuration on the third or fourth, and the bias supply was integrated on the 7th.  The PFC circuit is now operational, and has been tested up to a load of 85W or so.
