Here is part of my microwave oven transformer (MOT) collection. My stash of MOTs has grown since I shot this photo. All of these were salvaged from 120V/60Hz ovens. The two little ones on the left produce 1900VAC at about 1200VA. The two on the right put out around 2400VAC at about 1800VA, and were eventually incorporated into my twin MOT Tesla coil power supply.
