The high voltage regulator tube is the possible source of X-rays, not the rectifier. The rectifier has peak voltage across it when it is not conducting. As a shunt regulator, the HV regulator has the regulated high voltage across it when it is conducting, and current that varies oppositely to the CRT current.
That's my understanding as well. The 6BK4 is the source of X-rays. And thats in an open topped enclosure!
