When color TV was new, RCA made available the special needed parts. These
really included only deflection yokes, convergence coils, and horizontal output transformers, though others
could get the color transformers as well. Everything else could be standard parts, at least for sets using 21AXP22s and later CRTs.
RCA actually encouraged others to make their own designs. They didn't care ... they'd
get the royalties anyway. At least, if any of the sets actually sold.
