Questions about a B&O Beogram 2000 turntable

Recently came across a nice Bang & Olufsen Beogram 2000 that caught my eye, at a good price. It had been meticulously cared for by its original owner, transfer screws and rim brakes always set when it was put away, etc.

Only problem with the unit is that it spins slightly slow. Not incredibly slow, just slow enough to notice. The speed is constant and doesn't vary, it's just slow. I'm assuming that it has sat unused for a long time and therefore needs a new belt, but wanted to get some opinions. I freely admit that I'm normally a user of direct-drive tables, so my experience in the care for belt-drives is more limited.

I read in the user manual that the table has pitch control of +-3%, but I can find no way on the unit to adjust that. Is there a way to adjust the pitch, or is it simply that I need to replace the belt and that's the only thing I can do in hopes of returning it to proper speed?

I welcome any comments/suggestions.

Is it the 1970's type (that uses the SP10/SP12 type cartridge) or the 1980s type (that uses the MMC1/2/3/4/5 cartridge)?

If it's the older one, the speed is altered by a thumbwheel on the left hand side of the plinth, that sticks out from under the wooden trim near the back. If it's the 1980s type, the speed can be adjusted, but only by tweaking the relevant pots on the internal PCB.
 
It is the newer type, and has the MMC3 cartridge/stylus.

Is it a hard unit to crack into to get to the pots? Is there a service/repair manual available?
 
B&O are generally nightmares to get into. Seems they had a hide the screws philiosophy. That, and prepriatory styluses makes them a rich mans toy, not serious equipment IMO. But I always enjoy the sound of their speakers.

It's easy enough to get into - undo the two biggish screws on the underside near the front and the top plate lifts off. The PCB is under the area where the cartridge sits when the deck is off. Watch for the tiny control PCB behind the 'start' button on the friont panel though, as this needs to be slid out of its locating holder, and the connector to the PCBs for the other buttons disconnected, before the top plate can be lifted and slid out.

PM me with your email address if you'd like a copy of the service manual.
 
Much thanks for the helpful info. I was able to easily remove the cover and adjust the speed pots, so she now spins at a correct 33 and 45.
 
I've got a Beogram 1800. I know there are "rim brakes" under the platter - they're supposed to lock the table during shipping.

How do I get the platter up to lock the brakes? It doesn't seem to want to lift.
