The second part perhaps is a thermistor. Does anyone understand why thermistor, and why there?

I don't know what the purpose of that 'NTC5' component would be. 
It was originally on Akula's schematic however.

Usually thermistors go straight on the heatsink. But i also can't figure out how this work on here!
Thanks anyway

It seems it is a thermistor, and it was meant as over temperature detection for
the series tank capacitor to detect over current in the tank circuit?
'NTC' if that is the case would indicate 'negative temperature coefficient',
so the thermistor's resistance would drop with an increase in temperature, loading down the
resonant tank circuit. This may not be a critical component in such a case. 
He is using the symbol for a thermistor, so it may have been put in there for over heating / over current
protection.

If you build this then you will see that its not strange at all. (I mean the snubber) In fact is the most important part of this generator. The 2,2nF combined with the diode capacity, make a tank circuit with the half yoke primary inductance, and load 24V dc with the high frequency oscillation (when mosfet closes). In my case with 12 turns half yoke primary is about 600Khz... As i have told again, it behaves exactly as a Tesla spark gap but in solid state!
This resistance serves as to help the cap to discharge when mosfet opens. Its value determines the currents which pass through the mosfet...
7.5 ohm is for 25V dc pwr sup. If you raise voltage you have to raise also this resistance. At 300V is about 90 Ohm

hi Jeg,

I think you are right on using resistor 7.5ohms in parallel with diode for around 25volts supply.I do admit it's a uncommon setup.

150 ohms is more suited for around 600volts...1200volts coupled with hv diode.
