They probably did that to act as an electrostatic shield to the wiring in the base of the HV rectifier. Otherwise the sharp ends of terminal lugs and wiring would cause corona discharge, which might make radio frequency interference. I suppose that there is normally a metal cage to keep it out of reach.
