Re: Philips 25kv EHT unit.
In case you are wondering what's inside the can, please see the attached pictures.
You can clearly see the three EY51 rectifier valves and some capacitors of the tripler circuit.
It is more or less a ringing choke configuration with a feedback winding.
If the circuit works as intended, the output voltage is fairly constant @ c. 25kV.
