Happy Christmas hollidays ! I did not measure my PL519 at the time. Also it has not been used for more then 20 years now as i play with full range ESL’s. Anyway, you are in the right track. Do you have 1 or 2 speakers now?
As the sound is stéréo ,i builded two units.
I'm waiting for two 220 12v 10w ferrite transformers.
Please show your speakers at work.
It will bé great.

If you would like to have it started automatically you need to build a starter.
Automatic screwdriver ? Or an other device ?
Yes Lampie 519 ,the relay.Yes. Look at the Magnat Plasma speaker.
But at flyback.org.ru i readed that some Gu50 units start from themself.
Even at Diy.audio i readed that someone do with 600v PSU.But in this case perhaps is it an arc speaker(between two rods).
So if i don't find to made without, i will do like Magnat.
Lampie 519, i was TIG welder with automatic machines.They use HF for starting the arc.
Other point :with TIG process (for steel welding)rod is at the négatif pôle and pièce is at the positif pôle, current walk from pièce to rod and electrons are walking from rod to piece.
In plasma speakers case it is the opposite...
Any view on this ?

Hello,
Here is my starter device.No more screwdriver is needed.I silver brazzed à little ceramic pipe tought the Faraday cage.The little rod is fully insulated.
It's works well.Just push the ceramic connector.
Even it's possible to play with the flame.

Hello Lampie 519,i have a question for you but no matter with plasma:
You interest to ESL.
So is it possible to build a directly push-pull drived ESL with 6l6?
What are good tube to build that ?
Regards

Hello Marco, the 6L6 can be used for a ESL headphone amp but not for full range ESL's. You need tubes that can handle the power supply voltage without any issues. And a 6L6 can handle only 500V max. You need tubes that can handle 5KV.
But i think there is a thread dedicated to DD amplifiers here somewhere.

Hello,
I have received my little frequency meter(10€)
I hoped around 35 MHz, but In fact:
Coils where soldes as 10uh ones.But on a side of them it was written "L22". Now i know what it means.

Hello,
I received 2 Visaton Tr84 transformers for modulation.
I wirered them on 6W and 8Ohms pins.
It works fine,the sound is very good.
This plasma speakers projet is now almost finish:
Perhaps 1 or 2 things to review.
Thanks Lampie 519 for your help

Hello,
Parasitic Suppressor.
I don't realy understand how it works.
See picture please : Is it wrong or right ?
If it's right,i notices that the impédance stays Low.
Which capacitance should i choose to design à parasitic suppressor ? Anode-cathode ?Anode-grid?
