The color CRT was probably drawing 1.8 amps instead of 0.6 amps, but that shouldn't have cause a huge drift.
The electrolytics were probably increasing in leakage as they warmed up dropping the HV used for the emission test.
Congratulations on figuring it out and repairing your tester.
Did you get the set?
