Motorola built slightly different versions of that chassis for about four years running. TS914,918,921. Your's is the TS921, the last of the run.
Naturally, the first two runs used 23EG's. The last runs used a 25X or 25A type. The chassis was really reliable, the CRT's, not so.
40+ years ago, I installed a Zenith ChromaColor CRT in a set like yours. The original CRT was an Admiral, EIA 101.
The set owner said that the picture was good for about two years and went downhill fast.

Twas the admiral jug that died fast right? If the chassis killed a CC-CRT in two years something had to be very wrong.

The original Admiral sourced jug is the one that failed. AFAIK, the Zenith CRT was perfect.
That Motorola chassis was very reliable, more so than many.

That sounds like an Admiral CRT. Motorola at one point made a deal to buy Admiral CRTs for some Moto sets. The engineers at Moto were all grumbling predictions that we would be eating a lot of warranty costs on those. Don't know what Admiral's problems were (poor evacuation? dirt?) but they were the first to offer extended color CRT warranties with their sets (2 years) and that really wasn't enough.

The Motorola set that had the Admiral CRT was a lower-end model with a inexpensive cabinet. The set itself never needed repair up to the time, the CRT needed replacing. Another problem with that chassis was the video output tube, 6LY8 was overtaxed and needed replacement often. No sub would work well.
Another quirk was replacement of the 6LE8. The replacement had to be a Motorola branded one, either a Japanese or GE sourced one. Using an RCA or other brand, the tint range would be affected.

Could be a strong possibility, that helped management decide to discontinue the manufacturing of TV sets. The Galvin family was still running the firm.
They probably made as much profit on a pocket pager as on a TV set, without the warrantee problems.
