An update the A2B neons didn't work, but: George Kerber sent me a few GT-NE6H1925T neons. I pulled two out the packet and installed them in the chopper, and wonder of wonders the correct waveform appeared at the test point.
This is a great step forward. The earlier neons I tried had way too low a firing voltage so both fired. These fired at about 95-100V with a sustain at about 68V and do alternate.
