I found a tube headphone amp kit on a Chinese website, I thought you might like to read about it
"Specification:
FE-6J1-2 tube fever plate pre-amp is the circuit schematic imitation design team Music fax X-10D, to be rational optimization, more stable performance than the original machine, 10% tube set increase. This board uses a single 12 V AC input battery, the processing circuit provides 6J1 tube required positive and negative voltage and voltage supply filament voltage.
Energy works: an open tube feeding the filament heating is started, when the impulse from zero-tension start to increase the hot filament tube, etc., also happens to boost boost finish, so this is the same with the 8 * 470 UF capacitor very clean filter, good power supply system will not have a buzzing, the filament is 12 V DC power supply, needs two tube is connected in series with a DC filament filament too in order Reduce noise.

For $1.50 more they will assemble it too! From the review looks like you need a beer first before assembly lol.
I am interested in the fact that its tube and it runs off an external 12v power supply. I want to build an external tube driven effects loop that also runs off a 12v AC power supply.

uses a single 12 V AC input battery?
Re: Tube Headphone Amp Kit
Wow, even Tesla doesn't have AC battery technology.
Tube junkie that aspires to become a tri-state bidirectional buss driver.
