The internal plug question I can answer. This is sort of a "junction box" where the AC cord coming in from the wall outlet connects through this socket to the clock. It also has a socket which the short cord from the radio is plugged into. This AC supply is not switched; it is on all the time as long as the set is plugged in, so the clock can operate normally.
I doubt that potentiometer is there to regulate the 5Z3, but stranger things have been done to radios. Just exactly why this extra potentiometer is there, and what someone intended for it to do, can only be determined by someone familiar with vintage electronics, knowledgeable in reading schematics, and who knows what he/she is doing. No offense intended.
