It seems it rectified the entire 25kv from H.O.T. with large coil winding (no high voltage Multiplier employed ?)

First large screen color all solid state. The solid state HV rectifier consisted of a stack of lower-voltage diodes. The shape of the fins was designed to equalize the capacitive current and therefore the transient voltage across the individual diodes from the top to the bottom of the stack.
