Metallic object directly connected to the chassis. By the time your set was made most AA5 were made to UL standards...Which dictated the chassis not be directly wired to the line (instead a current limiting 'safety resistor' would be placed in between), and that no metal objects with a conductive path to chassis be placed on the outside of the cabinet...Chassis bolts on these sets usually threaded into plastic fittings on the chassis or were contained in the cabinet.
Pre-1950 is where most non-UL sets were made, but there were some non-UL cheapies made after that...
I have a 1940's Sonora AA5 radio/phono that has electrically hot toggle switches for the motor and the radio/phono mode...The pickup arm is hot too.
Metal cabinet hot chassis TVs were subject to the same rules, and analyzing the effectiveness of the compliance measures can be interesting.
