Good evening everyone
well I’m very excited as I bought a wonderful Beoworld RG 900 de luxe at auction today for only £85.
It’s in great aesthetic condition. It even came with the wiring manuals.
The sound out of the speakers is quite lovely. I’m a radio presenter and appreciate good audio quality.
Currently I have only got the radio to work.
The Garrard deck appears to be dead. Is this a common issue?
Could it be a fuse gone or a cable disconnected? The unit is in such good shape generally that my gut feeling is that fundamentally it works and there’s a simple fix!
or am I being totally naive??!!
any guidance would be hugely appreciated as I’d love to hear how warm vinyl would sound being played out of it.
If it’s not reparable, is it easy to replace? If so, is there a model of choice to do so?
once again, thank you in advance for any help. I’m really in love with this unit and now want to get it fully working.

I rescued one of these some years ago,on it's way to the dump!!! As you say,wonderful build quality and performance.
Mine had the original B&O turntable,but I understand that B&O sometimes supplied them with Garrard autochangers too,so your's may be a factory fit.
Which Garrard turntable is it?
They are robust machines,and many parts are still available.I wonder if your's has suffered seized motor bearings or perhaps the idler wheel they employed has perished,so not providing traction?
The RG900 is a joy to work on,being designed as is most B&O to be accessable for repair work.
You will need to remove the radio/amplifier assembly as a unit to gain access to both that and the release clips for the turntable chassis.The wiring looms are unpluggable.
The securing screws are underneath the cabinet.
There may be a service manual on site,but you will need to upgrade (recommended)your membership level for access.
Regards,
Nick
Thanks so much for taking the time to reply.
I don’t have the model number, I can’t seem to see it anywhere visible.
I will take it apart as you suggest. I already have the service manual.
Because there was no sound being generated when I ran the needle over a record, I remain hopeful that it’s just a connection issue rather than the motor. What I mean is, even if the motor was broken, the needle should still generate some sound manually.
We’ll see. I certainly don’t have the know it all do replace the motor.
beyond that, do you know anything about what kind of deck I could replace it with? I am assuming I’d have to install a pre amp too?
i appreciate all this is stabbing a bit in the dark!!
thanks again
Does the turntable platter spin,but you just have no sound?
Replacing the whole turntable assembly would be a last resort,and I imagine that the mounting board is designed to accommodate the Garrard,otherwise you could consider fitting a Beogram 1000.
It's well worth exploring further inside,there may be an obvious answer once you get in there.
No need to replace the motor if it is seized,they can be re-lubricated in most cases.If the idler wheel is perished,you can probably find a "new old stock",or salvaged item to replace it.The wheels can even be rebuilt with new rubber if necessary.
Thanks Nick.
i am literally getting nothing happening - no sparks, movement or any sign of life. It almost feels like I need to put the plug in! I’m hopeful that when I open it up later, I may spot something blindingly obvious like a detached cable - just something which will spark it into life!
I’m guessing that all the motor stuff is only really relevant if I am at least getting some movement from the deck?
it’s funny, when I bought it, knowing the turntable was dead, I thought I wouldn’t mind. But now I have it at home, I’m really keen to get it working.
I have this suspicion that vinyl will sound just lovely on it!!!
So I (poorly) attempted to dissemble the unit. I managed to lift the tuner out but couldn't clear it completely as there were some wires (speakers?) which lead straight into the unit, without a plug, so I couldn't detach them! Anyhow, I had a good look under the turntable using my phone and I found what looks like a couple of loose wires.
I cannot help but think that there is no power going into the record player. There's one red wire, with a flattish connector which connects into the back of the tuner.
Then there was a blue wire, not connected to anything, and a beige wire with two wires inside, again not connected to anything.
Both the blue and beige wire appear to be attached to the big round plugs in the back of the unit.
Does this mean that, perhaps, the record player is not currently connected to anything, and hence is not powering up?
I am totally out of my depth here!
Thank you...
The big round plugs are for antennas.The spade connectors too:

The speakers could be plugged into the DIN sockets at the back or to a 5-pin DIN inside the chassis, next to the tuner and the antenna sockets.

I've sent you some pictures which should clarify how to get the turntable out.This will let "the dog see the rabbit" as it were?
All the connections apart from mains power should be detachable at the tuner/amplifier,so I'm a bit puzzled about the "hard wired" cables that you can't detach there,but once the turntable is out things should be much clearer.
Yes indeed,you won't be disappointed with the sound quality from vinyl.Can you tell which p.u,cartridge is fitted.I imagine it's not B&O,although they could be employed by using an adaptor.
Keep us posted sir.
I've had another study of the service manual,and the wiring for the turntable is rather more complicated than I remember.Apparently,a Garrard AT6 turntable is employed in your unit,mine used a B&O deck.
There is an RIAA pre-amp module,which seems to be powered from a separate transformer.
The screened(braided) cable is indeed the signal feed between the pre-amp and the main chassis.
It seems as though you have some soldering to do!
Have you been able to remove the turntable and praps take some more photo's within?
