My memory (which might very well be wrong) was that one of the principal

Close. Most HV rectifiers were inside steel boxes, with the flyback
transformer. The HV shunt regulator was exposed on some chassis, and
were the worst source. GE made replacements with a thick, lead
impregnated synthetic rubber coating to modify TVs built with those
chassis series. Then changes were made to the entire HV system to
eliminate the HV shunt regulator on later designs.
