small valves

[Paxton Hoag]

I am interested in a schematic, too. I think I have some of those
small wire lead tubes left. They are quite interesting. It would be
fun to do something with them.

I like radios but to keep this a little on topic are there any analog
computer designs that could be built with a small batch of small
tubes?
