Suspect the 46VAC is normal, its low current, not a hard voltage. Bakelite cap no. 47 is across the power line tapped in the middle to the chassis, its acts as voltage divider of the mains voltage. Your meter only needs a small current to register a reading.

The red terminal is for a flying lead antenna. A 10 ft. 22 guage wire should do nicely. A Philco doublet antenna would connect across the red and blk terminals. Gnd terminal can be connected to outlet cover plate screw but will have some AC leakage current coming through the no. 47 cap. Prefer to leave it disconnected.

Should get excellent reception with just a flying lead antenna.
