Plasma speaker schematics recommendation

[Electric flower]

I want to build a plasma speaker, i have searched for schematics and videos, and there are plenty... tried to contact some people but got no reply.
As there are many schematics i don't know which one works the best. So if anyone who has ever built one can give me advice or tips i would be grateful.

Budget  around  50ish $ (i have flyback transformer and few heatsinks).
Not necessary, but if possible jellybean parts.
Signal would come from mobile phone.

From the tv i salvaged i also have components:
TDA8356
TDA7057AQ
SEC3S0680RF B 837
TDA 6107Q
SEC C5386
SEC L836
(some other passive stuff)

I don't have scope so i'm very limited with testing and measurements i can do.

And offtopic, can i use block of aluminium without fins for air flow as heat sink effectively as one with same dimensions but with fins?

Fell free to ask for more info if i have forgotten to mention something, and sorry for bad English.

What technology do you want to use?

If you can get a 10-30KV triode tube (i.e. soviet 6C20C) , then you can make a super simple one.
Flyback's + to a sharp point a cm away from tube's anode, - to tube's cathode, grid to control circuitry.

The (dead simple) control schematic to translate the cellphone signal to the tube's grid:

You'll need +12V and -12V, tie the ground to the flyback's -.
Plug the cell phone audio into SND port, attach the tube to the GRID one, and the spark would make music after some tuning (center the input signal, then tweak the tube side POT until the sound is best).



The sound gets much better once you put everything onto a solid layout and make sure no HV noise is going around.

This isn't your usual PWM driven, multi-IC design, however.
