GE replaced the CRTs due to early failure rates. It was a new CRT design using a low wattage heater, light weight glass and a single ended connector. There is no separate anode connection. Within a few months of operation many experienced bad picture tubes and bad off-on switches. Many of the CRTs listed on ebay are the duds.
GE wasn't too particular about getting all the bad tubes back so some were stored around TV shops for years. New GE replacement tubes should have a blue monogram on the very end of the tube connector and a number-matching warranty card.
The 8" RCA was a better basic design with a power transformer, conventional tubes and more B+. It had poor sensitivity and early vertical problems. Both had 2 video IFs, but RCA had 1 IF in the tuner and had to skimp on the tuner gain as well to keep it to two tubes. The 9" GE used a conventional Oak tuner.
About the same time, Admiral made a rectangular 10' that was much better. Unfortunately, it suffered from bad tuner design.
