I agree. There is a socket on the back of the power supply chassis into which a mating multipin connector, at the end of a multiconductor cable, would be inserted, with an AC outlet next to that socket. This could have been a power chassis for an amplifier or a radio tuner; hard to tell just by looking at the thing. The entire setup indeed looks like a cobbled-together TV-radio combo, with the aforementioned power supply just left in the bottom of the cabinet for no particular reason.
