There's an interesting statement there:

"First mass-produced color TV with the three electron guns arranged in-line rather than in a delta (triangular) pattern (I'm not sure if this is true or not, but I can't think of an earlier one.) Also, as an aside, during development of the Trinitron tube, Sony had considered licensing GE's picture tube technology as used in the PortaColor. (The Trinitron is a single-gun tube, however, and was based in part on the earlier "Lawrence" (Chromatron) tube which was never perfected or put in production). "

I didn't know that these sets used such a picture tube, only knew them for their extensive use of Compactrons and that because of the compact nature of the chassis that many repairmen didn't care to work on them.

Actually Sony's Trinitron tube was Based on Philco's "Apple" picture tube.
