Toy12 Plasma tweeter Diy-6

Order 120W VR for step down high voltage.


Put resistors on wood rack and finish high voltage connection.


After long time debug a tiny flaming just pop out.
So far I could make sure my circuit of RF TUB amp. is workable.
But I still need to tuning work voltage and current of PL519 to improve flaming make it large.



Zoom in picture.


Re-modify working voltage and current 480V and 0.2A.
No sound modulation in and Just carry frequency radiation.



Modify flaming size.
