Up for sale here is this beautiful NOS NIB Western Union-badged RCA Type 83 mercury-vapor rectifier vacuum tube, dated 1958 but probably made well before then and just rebadged later. I tested it on my Hickok 533A tube tester, and it tested at 2350/2150, where 1500 is minimum good. This is a great tube and is guaranteed to work well for you. Please see my pictures for details.US shipping and handling is $5, and international is $24. I accept Paypal. If you have any questions, please ask.I have a number of other tubes & sockets, collectibles, Magic cards, and vintage electronics listed--feel free to take a look!
