Hello everyone,

So here it is, I am new to the forum and I need help!
I just returned from vacation at my grandfather's place and he showed me a turntable from the brand Sony model HMK-70, it's a turntable with a radio and a cassette player.

The big problem is that once the speaker is connected, nothing comes out and I don't quite understand the system behind it.

If someone could help me, that would be very nice.

Configuration: Windows 7 / Safari 535.1

    Well, it's a vintage "hifi system," the stylus might be faulty, if you put a 45/33/78 RPM record and the speaker doesn't produce any sound, then you need to change the stylus.

    Thank you for your response,

    So it’s not just for the discs.. No sound comes out when I turn on the radio or a cassette. Now I’m wondering if my grandfather properly connected the cable with the DIN 41529 plug because that’s the first time I’ve seen this.. Can I upload a photo here to show you a bit because I’m not really managing.. :-/ Logically, we should connect two speakers but next to that, there’s like a small transistor, well I don’t know what it’s called ISS and you choose either Speaker A or B.. Can we connect both at the same time or not?

    And then I have another question.. What is the diameter of the belt for the turntable because it’s broken with age..

    Thank you again for your answers
