I have a tube from the ENIAC.

More likely a 12AV7 or maybe a 12AZ7.

It's a shame, but I lost a two-tube circuit board I once had from a 50's
computer - a Bendix I think - with two 6146 beam power tubes, part of the
drum memory head driver circuitry. *Maybe two in parallel to feed a head?

A "pointed little head"?

What a concept.
