A friend of mine is getting heavily into building radios, digital clocks (using nixie tubes and/or miniature vector displays), etc. from tubes. I've been thinking that some of those nifty prototyping boards like we used in high school would be great for him to use for testing new designs. The ones I used had a base made of clear plastic with an array of holes in the top which lead in sets of 5 or so to a common set of metal contacts. There were dozens of sets of contacts on each board. The tubes were mounted in sockets on small squares of PC board with traces leading to pins along the edges. These pins would plug into holes on the base, and you would plug wires into the other holes on the same contact strip to connect something to that pin. There were also inductors, variable caps, pots, etc. on small boards. Any idea where I might be able to buy something like this setup these days?
