Best Era for CRT tvs?

[N2IXK]

On the basis of build quality/reliability, I'm another vote for the early/mid 70s solid state sets. PC board technology had improved with the use of fiberglass boards and solid state parts generating a lot less heat. But the boards were kept to small individual modules to aid troubleshooting, and still mostly discrete parts or simple linear ICs. The chassis itself was usually a full stamped steel holdover from the tube days. Heavily built, often transformer operated linear power supplies. CRTs got improved phosphors and black matrix screens, and delta gun color tubes were a fully mature technology, at the top of their development.
