Of course Im going by a few brain cells myself, probably compromised by all those griplets I soldered on the later small-screen GE's

H-3/HC were 69/70, so 1971/72/72 is the H-4/10HD. The 10JA PortaColor came out in 1974, followed by the 10QA in 1976 or 1977. We know that 10HE tube PortaColors were made as late as 76/77 - Andy has one....
