Stable work I have achieved with 13+ volts at the input. On 3 neon indicator and a small neon bulb at the same time is spent 1.4 watts. The essence of the lifting stresses to fill up the rising edge pulse on the coil. When voltage is below 12V I strongly sags load voltage (from 250V to 160V), an incoming 14V voltage sags within 6 volts.

The scheme was useful, thank you!

Out on Google Translate.

Can I use a BJT transistor instead of IRF740?

how do you select which number to power?
how many nixie tubes can you drive with this circuit?
