I'm thinking about to test a variable HV unit to load the diaphragm.
Did anyone try this:

Hmmmmmm........ Intersting !!
This type of stuff simply wasn't available when i built my power supply either/or they were just too expensive.
Nice size core in that thing, I may just have to get a couple of those and try them out as well!!

My latest bias supply used a used EMCO unit, a $15 variable DC power supply with voltage readout (a little naked board), and a 20vac transformer.
You put 0-15vdc into the EMCO and you get out a nicely proportional high voltage. The EMCOs are trustworthy which is possibly more than can be said about the "ozone generator" supply OP posted. Likewise, really great to have the easy adjustment and voltage readout.
BTW, terrible mistake buying from that Chinese eBay: you will receive a million spam a day until you cancel your email address. Listed products may be good and a bargain, but see if you can use a temporary email address.

I think I will order one of those... There is also a stronger one available:

hmm hi sailstra, same topics as on the FB page 🙂 i dont expect very different answers though. hihi i think to expensive and potential dangerous.
Combine this high power high voltage supply with some metalized film and you may have some nice firework.......
Yes indeed.... So have to take care with the bias voltage when installing and assembling the test of this thing.
Hi All
I bought a CX-50 just to try out. It is labelled as a 2kV to 10 kV supply, not 1 kV to 10kV as shown in the picture.
The one I received goes from about 2.6 kV to well above 10 kV when driving a 100 M ohm load - well beyond my 10 kV meter fsd. Don't know what the regulation is like - yet to find out.
A bit scary for my tastes, especially given the 5 mA current capability.

Hi Geoneer
No. I'm sure it would be fine, just has a lot more grunt, both voltage and current, than necessary.
The normal Cockcroft-Walton multiplier is perfectly adequate, it will bite, but only 1 or 2 on the crocodile scale. This thing is lethal - definitely keeping one hand in a pocket.
