You are bidding on a group of 4 Western Electric Type 430B Cold Cathode Neon Triode radio/audio tubes, new old stock (NOS). They are in excellent condition with their original boxes.  They are identical with a date code of 6513.  The deep red coating is in perfect condition on all of them, as these are often encountered with cracks or chips in the coating.  Shipping weight is 12 ounces.  They should be great for your projects.  Please see my other auctions for more interesting radio and audio items, and tubes.
