I designed this circuit to make 60 volts ac peak to peak secondary toroid winding. If NE2 Neon is .5 milliamps 100 neon lights in parallel will be 50 ma. 2.125W is not much power for a toroid I have 7/8" diameter and larger.

2 D batteries can deliver 8a max. Short circuit = 25.6W. 2W should be ok.

I don't know much about toroids. I have formulas for EI laminate transformers they need a certain number of primary turns to be happy what about toroids? I need a starting point for primary winding is there something better than guessing? I have #24 enamel coated copper wire to wind toroid with.

I did math for circuit to run at 1460 Hz is this ok for a toroid?

Suggestions?

This is a long over dew project I bought these NE2 Neons 30 years ago there is no resistor attached to the neons.
