I have NOS tubes up for auction on ebay. This is an internet auction site. Check out what I have for auction. An auction allows the marketplace to bid on items. You can never tell what the final price may end up at - some real good bargains can be obtained by auction.
Military versions are acceptable.
You may have the tubes that I want to buy. Once I know what you have, I may be able to make you an offer if you have what I want. I appraise the value of NOS tubes. I will give you a true market value of how much each tube is worth. I have the expertise to identify different varieties of the same tube type by the same manufacturer.
