Mini SSTC CW

Based off Steve Ward's "mini sstc" running CW.

Half bridge of IRFP260's driven by UCC37322/21's. Antenna feed back feed though 74HC14. Resonate freq: 250-300kHz. Running from rectified 120VAC approx: 170VDC across the half bridge. 1000uF mains smoothing cap. 8 turn primary.

Not sure about the current draw yet, variac doesn't sound too happy (huge amount of 60hz hum) but that is probably due the the variac's contacts needing a good cleaning.

Camera: iPhone4
