Waarbij ik de 13V zener vervangen heb door een 82V versie en een chinese voltmeter module over de uitgang heb gezet die tot 99V gaat. Hiermee kan ik zeners tot 82V testen. Een oude telefoon adapter verzorgd de 5V

It's the rule that you live by and die for It's the one thing you can't deny Even though you don't know what the price is. It is justified.

@Blackdog, op de gelinkte pagina staan wat adviezen voor hogere spanningen:

High Power / High Voltage?

Note! This circuit can be quite usable for higher power applications, and will oscillate reliably with a larger (high power) version of Q1 like a TO-220 darlington type. Remember it regulates INPUT current, and will provide a fairly regulated amount of power to the high voltage output load. It can be used as a simple 4 watt fluoro tube driver with a 12 volt input (for example). If you try this, try these values;

Q1 = TIP122 darlington (see note)
L1 = 470uH 500mA ferrite core inductor
D1 = 1N4937 600v 1A fast rectifier
R1 = 4k7
R2 = 3.3 ohm
R4 = 56k
CLOAD = 0.1uF (not critical) but must be 630 volt type

Mijn versie, zener aansluiten, dan drukknop indrukken om te testen.
