Aah! The Good old days:
GE 1977 -1980 Ate yokes and flybacks, The CRT's weren't much to brag about either.
Sharp of approximately the same vintage ate flybacks like kids eat candy...
Sony went through a rash of bad CRT's at about this time.
Zenith System 3 series one was OK but when the 9-160 series 2 sets came out was getting like 35 at a time with every thunderstorm, the hot / cold ground system did not like spikes.
Zenith system three version 3 with the 9-191 / 214 series of boards were better except the remote power supply was very likely to be damaged by spikes.
The last Zeniths I worked on was pure junk could not feel safe the CRT would no fail on the dealers showroom floor. The projection sets were bad to arc and destroy power modules...
Rarely seen a CC2 flat chassis except for the occasional triac failure on the remote sets.
