Default Speakers: JanZen, Type Z 412 HP, any good?

Hi all!
My nephew bought some "Junk", "HiFi-audio stuff" or how ever you like to call it.
Among that stuff is a pair of american speakers, named "JanZen Type Z 412 HP".
They were fixed once, the seller added a bill.

Interesting is, that they are good for 110-240 Volts & 50/60 Hz.
The electrostatic speakers/tweeters are something rare in our days.

Anybody out there with experience with that stuff?
Are they any good and valuable?
Are they worth to repair, if anything is broken?
There is not much about them on the internet, how's about
spare parts?

Thanks in advance!

I don't know them at all, but I googled and they do appear to be serious HiFi speakers rather than junk.

See https://duckduckgo.com/?q=JansZen+Type+Z&ia=web, https://www.stereonet.com/forums/top...ostatic-z-410/

They're American.

They may need the mains supply to generate a high voltage DC bias/polarising voltage (300-500V ?).

They may also have a step up transformer to increase the signal voltage.
