100 NOS RAYTHEON JAN 6418 Subminiature Twin Triode Tube - San Antonio - Bonanzle
6021 is a small dual triode. I have been experimenting with them in a guitar preamp circuit. It will eventually go inside the guitar. They can be stuffed into an 8 pin round IC socket with a little pin bending.
The data sheet is too big to attach. get it here:

How about the 5670, which is in the little peanut-size envelope like a 6AK5.
5670! Yes! That's just might be the one I need. With that p/n, I found other possibilities... 6N3P 2C51 WE396A. With your help, google is my friend again

Duncan amps TDSL is also a great piece of kit for this. If you know the base and envelope you want (thery are standard) you can use its search feature to identify only tubes with those features. Of course, you need to know what base and envelope code you are looking for, but once you have a lock on that it makes finding a suitable tube easier.
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.
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
Pay attention to the circuit if you use 6J6, he's prone to break out into oscillation if you look at it sideways.

depending on the intended sound, the microphonics might make it sound amazing
He should open a new thread telling more about it.depending on the intended sound, the microphonics might make it sound amazing
Maybe he will do in his webpage.

...so I guess that would be the first tube pickup.

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..
