I could see RCA shipping CRTs with yokes already mounted on them, and with the convergence circuitry connected up to it, as a single package. With the convergence adjustments already done at the factory. and in the field: "mount this board here, and connect these connectors here".

Every time you moved one of these sets, the convergence was out anyway, so much better the service tech had practiced in his shop before he had to do it in the customer's house.
I strongly suspect that RCA had production problems with getting enough CRTs made to meet the promised delivery date. The big lump of a TV set had to ship via freight, while the smaller CRT could travel much faster.
Legend has it that the 15 inch color CRT early production had more rejects than good tubes. As soon as RCA had the larger CRTs in production, no more 15 inchers were built and these early rejects were used to fulfill the 7 year requirement for replacement parts.
