RCA and Dumont in the early post-war were trying to show off what TV could do so they tended to over engineer their chassis. It was not going to market if it had JUST enough to work properly, it had to have as much stability and performance as it could. RCA also was allergic to stuff the did not hold the patent to like the tube count reducing inter-carrier audio (IIRC they were the last to adopt it).
Look at a 630 chassis 10" table set....About 40 tubes in those too.
