cleaning the pins of NOS tubes...bad idea?

I'm not a tube old-timer, but I clean my tube pins with either Caig Pro gold, Flitz, or whatever appropriate product at hand. I then apply a thin layer of contact enhancer, in this case Sil-clear, fine silver paste to insure best contact. As elsewhere in electronics, clean, tight, connections are job one in trouble free use of audio equipment. Do use clean hands or gloves when handling your tubes, however.

It isn't a bad idea to clean the pins from time to time. Hopefully the market will go towards creating tubes with gold-plated pins:-)

For heavy oxidation, I use a dremel fitting with a polishing wheel and jeweler's polishing rouge. Use a very light touch.

It is a good idea to make the contact as clean and smooth as possible, the above ideas are good. I recall that Andy Bouwman also sands the pins in the tubes that he sells.
