Plasmatweeter

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 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.
