Perfect! :) Lets see If I can fix this wonderful B&O

Funny thing - I just had a restoration project of a BC1800 and it had the bolts missing too.I believe that's because it's so hard to figure out how to open the unit if you don't have the service manual. Someone had obviously been messing around there before me and removed every screw, hoping that would help to open it :)

Luckily, the transformer was not damaged in the delivery, only small scratch marks on that same spot.

Got the new transformer installed and it cured all problems!

Now for the next problem: the turntable motor was stuck, I removed it, opened up and cleaned / oiled all moving parts.

Re-assembled it and now it works and spins, but.... slightly slow! :(

If I let it playing for 30 minutes or so it gets up to regular speed, so... what could the problem be? The oil I used would be too thick? Ae any other problematic parts? This is the AC version so I do not see much to adjust besides the motor itself...

Any help would be very helpfull!

Wrong oil and wrong lubricating method.
Keep in mind that these are sinter bearings. When the motor is running oil is pulled from the pores in the metal by capillary action.
Any oil added from "outside" (the conventional way) will be in the way and pressed away rather fast.

You will have to clean out the old oil from the bearings = acetone bath, and let airdry.
Then submerge the bearings in spindle oil with the right additives for sinter bearings and draw a vacuum until bubbling stops (6-24 hours).

Google Oilite bearings - it's interesting reading.

Hi Martin,

what particular oil would you use with Beogram bearings? There is a variety of opinions around.

I have used Mobil Velocite 6 with good results.
