Interesting. On a related note, in 1969 we pulled a (then) late model GE into the shop with a really bad color sync problem that couldn't be fixed in the home with tubes. Noticed an NE-2 neon bulb in the burst area of the circuit board and tried replacing that, and it fixed the problem. I don't remember the details of the circuitry as GE was not one of our store's specialty brands. But the NE-2 was involved in the burst gate circuit.
