Beogram 3000 (5211) grounding

[Pavel]

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

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

[Pavel]

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…

[Mark-sf]

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.

[Mark-sf]

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?

[Pavel]

@Mark-sf

It does not work like that. You need to rotate the counterweight all the way in until it engages in a hole. Than you need to move the ring on the tonearm to the desired stylus pressure. It is in the manual.

[Mark-sf]

As long as the cartridge body (coils) is fine you can simply replace the stylus. The SP-9 was the elliptical version of your SP-7 and is available on the web such as https://www.lpgear.com/product/BOSSP09.html.

Hello!

Congratulations on your purchase of the Beogram 3000 turntable! It’s great to hear that it’s in good condition despite its age.

Regarding the issue with the grounding, it’s possible that the previous owner did not properly ground the RCA connectors. You can try connecting a wire from the grounding screw on the back of the turntable to the ground terminal on your amplifier or receiver. This should help eliminate the hum in your speakers.

If this doesn’t work, you may want to consider re-installing the DIN connector, which is the original connector type for the Beogram 3000. You can find a replacement DIN connector online or at a local electronics store. Once you have the DIN connector, you can follow the wiring diagram in the turntable’s manual to properly ground the turntable.

Regarding the belt replacement, it’s always a good idea to replace the belt on a vintage turntable to ensure optimal performance. You can find replacement belts online from various sources, such as Turntable Needles, LP Gear, and Thakker. Make sure to get the correct size belt for your turntable. When replacing the belt, be careful not to damage any other components, and refer to the turntable’s manual or online tutorials for guidance.

I hope this helps! Enjoy your Beogram 3000!  C4Yourself.com

Problem solved by changing the RCA connectors with new ones. It seems that the previous owner made some rudimentary connections there…

[Pavel]

Anyone know a reliable source for a belt designed for this turntable? I have ordered from two different companies and none of them fit, one has a larger diameter and the other one is wider…
