Hola Spike. It looks a very promising device!... now we have to wait until audio designers give to us the capability of this new " tubistor ". Good to learn about new things in electronics! Again, thanks!
 
interesting read Spike, thanks for sharing
 
Don't jump the gun gentleman, the vacuum transistor is still in the research phase. So we only have to wait for final research designs, ramp up to large scale industrial production, expensive first run designs, exploding gear in the field, audiophiles claiming its the best thing since sliced bread, more exploding gear in the field, etc.
 
Interesting stuff for sure. The much higher switching speeds are nice, not so sure how that might apply in audio.

Also, not clear if they are engineering these for amplification duties at levels suitable for an ESL audio amp. Remember that a good ESL amp will need to flow large amounts of voltage (as an ESL is voltage driven). A good ESL amp (such as the Sanders Sound System ESL amp) will deliver up to 2000 volt-amps into the high capacitance Electrostatic panel.

The ideal amp for an ESL is a direct-drive device (no audio step-up transformers required in the speaker), but talk about high-voltage, somewhere in the 2,200 volt range. Deadly to have in the living room. And no SS design has been done yet, only some old tube based solutions. See Roger Sanders article on his DD ESL amp.
