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:-)
cleaning the pins of NOS tubes...bad idea?
I am a tube noob. Just bought my first set of NOS tubes. I use Kontak, Deoxit, ProGold and the like on the connectors on my cables. I notice that the pins of most NOS tubes show significant oxidation. So...is it a good idea to use Kontak or the like on them, or do you just leave them alone?
