Yes, I experienced resets with a few tubes. Also the osc shows some spikes to zero without any tube, but with only the HV generator on. It stabilizes when the HV generator switches off. This evening I will try with just one tube, just to be sure.

I know, will make this 'permanent' as soon as I do some experimenting with neons. Thanks for the warning!

The board draws about 200-380 mA (at 12V).

I have a IRF540N at home. Would it be useful to test with this mosfet?
