And highlight overloads. Appears like one or more PU tubes might have drifted off focus or optical block/ Zoom tracking problems ? All told the 42 probably a loss generator/headache for RCA.
The 44's did seem pastel favoring yellow ? Some RCA receivers of the 70's & 80's also had the orange/yellow thing going on (could not tweak it out) high output phosphors ? matrix ?
