i'd annotate my photo, but RCA published a really nice cutaway diagram, so i will show you that instead.

Nuvistors found their way into some high end applications but transistors surpassed them in a few years, and they just faded away.

@tubetime@mastodon.social That's a beautiful technical illustration! I love the fine, shaded texture of the conical metal parts.

@tubetime@mastodon.social oh that's hella cute. I always used to think Nuvistors were external plate tubes, but it looks like the metal shell is floating and can be grounded on this one. Otherwise, the construction style used inside the Nuvistor is identical to that used in large RF power tubes... just... unembiggened.
