In trying to find a good assortment of tubes for my buffer I am wondering about the pins. I have seen many of the larger tubes that have 24k gold plated pins. Does it make a big difference in their sound or more for the anti tarnish properties? The reason i ask is in my case 6j1,5654w, EF95 class of tubes I seen only one seller that is selling the Russian Voskhod (Kaluga) plant tubes @ 24.00 a pair seems cheap enough, but I've bought some of these tubes(without gold pins) for a lot less from very good sellers and have been happy with them. I offered the seller of the gold pins a BIN 20.00+ shipping for a pair. He declined the offer but said he would knock off 1.00ea if I bought 3pr.
Aren't the pins made of copper? It wouldn't rust but could corrode a little but that could be cleaned easily from my experience. This would be the very first of this type of tube that I have seen gold pins. Are they rare?
