Roy, I have a collection of 7200+ different Receiving and transmitting tube specifications. There is nothing that even comes close to it. The number you are looking at is most likely an old Zenith part number. Look at the tube itself and see if there is a familiar number on it. If you find it, please let me know so I can make a cross reference to it. Ty Tiberius Kraemer BLUE STAR ELECTRONICS 3312 Silverton Rd.

Hi all. We ran into a few new/ old stock tubes by Sylvania. They are stamped 13-27681-4. Any of you guys remember what these are?
