Don't forget 6J6A and its many computer variants...cheap enough to select for audio quality, Rp 7k, mu 38. Shared cathode though, makes a good LTP

It will eventually go inside the guitar.

Lol. First time a tube gets inside a guitar's body. But where? Booster or buffer? Microphonics possiby a problem? I have to see that.

Pay attention to the circuit if you use 6J6, he's prone to break out into oscillation if you look at it sideways.

By the way Colt, the 6j6 russian variant is kinda crappy. Sounds ok but my God i thought i was watching a submarine movie, you know...ping...ping...ping.
Microphonic!

depending on the intended sound, the microphonics might make it sound amazing

He should open a new thread telling more about it.
Maybe he will do in his webpage.

you know if you want a nice microphonic tube to try it with, the 6418 submini is a nigh-perfect candidate. those things ring like church bells in a hurricane (and they're easily dampened with small rubber grommets if you feel the effect detracts from the sound)

Nope... Check this out, a tube used as a transducer - in this case a phono pickup.

Vacuum tube phono cartridge

This device was used in all sorts of other applications as well..
