As a matter of course, it is not a bad idea to touch the pins of the tubes themselves with a good soldering iron and GOOD solder. Dip the pin (or paint it) with liquid ROSIN flux, then hit it with a good iron and, ideally, a tiny touch of a good silver-bearing solder..... plopping the pins in Tweak or Cramolin helps, for the same reason it helps phono jacks not gold plated.... The mil-std sockets are a great idea, although if you are mechanically handy you can get a better contact by adjusting the sockets with a pair of fine jeweler's needle-nose.. Idea is to ensure an absolutely tight mechanical and electronic seal...
