NAGRA Chief Designer uses that PLASMA Speaker, picture of it and DIY
Mustafa Umut Sarac, Tue May 16 2017, 12:49AMHello there,
NAGRA is one of the best HI FI designers in the world and equipment goes for 50K and several times more. But their chief designer uses an plasma speaker for to listen the electronics. Here is the picture of the circuit and I want to build the same.
Please help me , I want to own a high end speaker like it.
FIND ATTACHHED OPEN CIRCUIT PICTURE. He uses Shuguang 807.

Ionofane used a cathode modulated class C rf oscillator at 27MHz.
cathode AM modulation does not allow 100% modulation so the arc of the ion source never extinguishes.
There was another in the late 70's that used a helium tank to supply the ion source so the quartz ionisation chamber lasted longer and helium has a much better expansion ratio so was louder

I suspect that is a staged photograph,
what kind of expert leaves the high voltage parts exposed,
generates high power rfi next to their test equipment,
likes to inhale vapourised copper,
and mounts it so that the heat of the valve softens the plastic ?

Might be a prototype?
