Indeed they do.  I even made up some adapters to adapt the original 4-pin socket to 7-pin miniature and 9-pin miniature tubes, which I detail here:

Hopefully, that link works and doesn't give errors in modern browsers that expect everything to be https which my webpage is not, yet.  ;)

When I made these up, there were minimum buys on the machined brass pins and on the PCB's, so I had quite a bunch made and still have a small supply remaining for sale as described on the page above.

Thanks much,
