This tube was used on a integral UHF tuner from channels 14-83 on my 1953 Westinghouse H-722K21 "Stratovision" 22" television console. I can't say what its exact function in the circuit was because I can't even find a mention anywhere that these sets had a full tuner not to mention a schematic of the device (my set was advertised as having two slots to add two "cubes" which would allow the set to pick up two new UHF stations taylored to your area). I would assume this tube was used in my set as some form of UHF RF amplifier however this is an educated guess. -Jon DeArmond
