Hello everyone,
I bought a vintage BEOGRAM 1600 (turntable) with no possibility of trying it out on an amp before purchase but it seemed to be spinning fine and I could hear the pickup sound from the stylus on the record.
The issue is that when I plug it to my BEOCENTER 1900-2 (on the phono input), I hear no sound at all, even when I push the volume to the max.
The BEOGRAM has a 5-pin DIN output, and the BEOCENTER has a 7-pin DIN input. Could this be the issue?
I used to have another turntable plugged to the phono input of my BEOCENTER 1900-2 (via a 5-pin DIN to RCA adapter, it was a modern TT). And it worked just fine, so the issue is most probably coming from the BEOGRAM.
How can I test if the BEOGRAM is sending any electrical signal through the DIN? Can I use a multimeter and check the pins? How should I proceed and which pins should I test?
Thanks in advance for your replies!
So I took this thing apart, did some continuity test between the head of the tonearm (without the cartridge) and the metal plates on which are soldered the very thin copper threads. It all seems to be OK.
The threads look very very thin and nothing is distinguishable. There is no insulation around the threads, is this normal? (sorry, i'm a noob)
What else could I check?

Oh yes, there are. The strands are lacquered.Which cartridge are you using?Does it actually touch the record, and does it track the groove as it should?

Ooh right, thanks for your reply.
The cartridge is a MMC 20EN and yeah it touches the record fine and i can definitely hear the music coming out the stylus.
I have tested with 2 cartridges (one has a damaged stylus, the other one is fine). No sound coming out to the amp, only from the stylus.
Maybe there's a short somewhere, maybe in the DIN cable...
