Default NE-51 Neon Bulbs

... Neat trick that you can do with the old variable capacity plate

tuner. Charge it to 30 volts with a neon bulb across. When you turn the
tuning knob to open the plates the neon bulb will flash? With only 30
volts how could it flash a neon bulb with a 80 volt trigger voltage?

I wish I'd thought of doing that. But I'm amazed it works, even with
beautifully cleaned insulators on your capacitor.

Good demonstration of relationship between charge, voltage and capacity.
