Sylvania 6DT6A NOS Vintage Vacuum Tube All vacuum tubes I have for sale come from a recently closed electronics service department's parts inventory.  All tubes with box included are NOS (New old stock) and have never been used.  These items have been sitting around on shelves for years; the boxes show their age with fading and some have tabs torn off.  I have no way of testing the tubes,  however I will gladly accept returns if you have any problems. Don't forget to check my other auctions for more vacuum tubes and other items. I will combine shipping whenever possible to save you money!  All tubes are shipped out in boxes for maximum protection.  Thanks for looking!
