Flipping through the 1960 RCA tube manual.. things like the 6BC7 or 6BJ7
independant triple-diodes (intended for FM disc. and color TVs .. signal
diodes), noval base. I'm noticing there are some interesting tubes such as the
6BN8 (fully independant twin-diode-and-a-triode) that might be turned into
2-input diode-logic gates.
6JU8 isn't here, must be later.
