1L6
Encyclopedia : 1 : 1L : 1L6 : 1L6
The 1L6 is a 7 pin miniature vacuum tube of the pentagrid converter type. It was developed in the USA by Sylvania. Released in 1949 for the Zenith Trans-Oceanic shortwave portable radio, this tube was in commercial production until the early 1960s but was only ever used by Zenith - in their Trans-Oceanics - and its short-lived rivals, such as the Hallicrafters TW-1000 and the RCA Strat-O-World.
Due to its limited use, the 1L6 was never produced in large numbers, compared to other battery tubes, and now commands high prices for good used examples.
