The 21CT55 RCA information that Steve K sent arrived today. Its much more detailed than the Sams
And my convergence chassis wiring matches the RCA schematic, which the Sams did not. Thanks again Steve K for the information!!! Now to start recapping and checking all resistance values, cleaning contacts, cleaning 50+ years of dust, etc.... And then theres the cabinet, which I guess I will save for after the electronics are finished.
