Hello guys!
I bought a Beogram 3000 (Model 5211). Really incredible condition considering its age.
However, there is one issue with it: the previous owner changed the DIN connector to RCA connectors. It seems that with Beograms, the grounding wire was connected to the DIN connector or something like that. Anyway, now because there is no grounding I have the familiar hum in speakers.
Any ideas how can I ground this TT?
Thanks!
PS I am also considering changing the belt. Any tips about it? Maybe a good source for reliable belts in UE?
Thx

Beogram 3000 (5211) grounding

Looks like a nice find! If you take the bottom off you will find where the RCA cables were attached as well as the terminal that is grounded to the chassis where you can simply solder a stranded single wire for your ground. As for belts, check out https://www.beoparts-shop.com
Thank you. I will try it. The ugly thing is that the previous owner did not change the cable completely. He just cut the original cable in half and tied another half of a cable with RCA connectors
While at it, is there another cartridge compatible with this TT beside the SP6-7? I also have a SP10, but it does not sound right and the tracking weight cannot be adjusted adequately...
If they spliced the cable, then you can connect the ground wire to the braided shield of the DIN cable. As to replacement cartridges, your SP-6 has a conical stylus. An SP-12 would be better; however, I do not know why you’d have an issue with the tracking weight of an SP-10. Do you have a stylus gauge? What range are you able to set?
@Mark-sf
The SP10 seems to be much lighter than SP6/7 and I cannot get an adequate tracking force...
It seems that SP9 would be a replacement.
I’d revert to the better DIN plug that has the correct grounding, separate from modulation.
What's with those guys who systematically want RCA fitted to vintage equipment anyway? ?
The SP10 isn’t lighter than the SP6/7. An SP12 is nice but mine was new old stock and its suspension collapsed very quickly. So beware.

I need the RCA plugs to connect it to the amplifier. I cannot use the DIN connector.
SP6/7 is 12 grams, while SP10 is ten grams. When I plug in the SP10 cartridge, the tonearm swings to the back and although I move the ring on the tonearm to the maximum scale, I still cannot get a good pressure, and the tonearm skates towards the outer rim. So clearly there is some incompatibility there.
The ring is just an indicator. You rotate the weight which is the cylinder behind.
Whenever I want to use a turntable that has a DIN plug (B&O, Dual) I use an adaptor. Better than chopping the original DIN off, surely?
