Yet Another Dekatron Spinner
Here's another dekatron spinner. This one is variable speed and
is all valve/tube technology. Uses valve rectifiers and a Z700U
trigger tube as a relaxation oscillator/dekatron guide pulse
driver. Will spin GC10B (and variants including GC12) double pulse
and GC10D single pulse dekatrons. 115V/230V 50/60Hz operation.

STL files and acrylic cutting drawings (DXF) from the web page.
