Modifying early postwar sets to show CBS color (29.16Khz) was only just barely "doable" if that's any gauge. John Folsom's CBS RX-43 prototype (really an RCA 9T24X) on working display at the ETF in 2004 was pushing the horizontal sweep output so hard that it had little red spots on the plate. This was apparently unavoidable in "normal" operation.
