Like previously mentioned you know where the yellow wire gets connected, the other one goes to B- (not the chassis.)
Someone probably clipped this off when the cartridge opened up or the wiring to the tone arm was broken and they chose not to have it fixed.
Under those circumstances the set would hum badly when you switched the mode to phono. You can verify this easy enough and find out if my theory is correct.
The isolating capacitors on the terminal strip were added in to prevent a significant shock hazard on the turntable surface, but in turn created another shock hazard on that strip. Small as the replacement caps are, I'd want to put all this stuff back in the chassis where it belongs.
