[ETS1979]

I have included a couple of photos. The cloth brown wire is the one that is disconnected on the other end. The black wire with the tape around it at the top of the photo goes up into the tone arm of the record changer. I presume that since there is no sound from the record player that brown wire needs to be connected somewhere, though I suppose it is possible that there is a problem with the cartridge. I can't see it but there may be a terminal strip on the back right hand of the tube chassis. Is this where it goes perhaps? Thanks for all help!
