I never saw one in a TV, but they are an old tube. Often used as an oscillator. I've seen amps designed with the tubes on the bottom and set in water. Looked really strange but added greatly to the tubes life.

The 6AG7 was a great tube in its day. Had about the highest
transconductance of any consumer-type tube as I recall. Originally used
as a video output amplifier in early black and white TVs.
