snip---
Some mil gear (eg PRC-41) has very small ceramic tubes -not sure if
they are quite as small as the Nuvistor but they must be close-
likewise some hearing aid amp tubes were pertty damn small as well.

- What was/is
the smallest tube? purpose?
RCA's Nuvistor - a family often found in late 1960s TV tuners and
some
test equipments. They are almost always triodes, and are really
small -
3/4 inch long, maybe 3/8 inch diameter, all metal. RCA made a few
half
sized Nuvistors, but never sold them.
