Beogram 6500 Issues

13 replies

Hi guys,

My second post here, so apologies for not contributing elsewhere. I've read a lot the last few days regarding the problems that I have, but so far I haven't found the solution.

Actually I have two issues with my Beogram 6500, and they might sound familiar to you. The first problem is that when the Beogram moves the tone arm to the record, it actually drops the tone arm next to the record. I already found that the actual drop position can be adjusted. However, there is not enough adjustment range, even after adjustment the tone arm still drops next to the record.

The second issue is that the 'sledge' that carries the tone arm does not move when the tone arm had reached its maximum rotation. Thus the record is stuck in the same position. A slight push starts movement of the sledge again and the record continues to play, until the same problem occurs.

What I've checked:

  1. Mechanical failures. I haven't found any, everything (including springs and cords) seams to be in great shape
  2. The belts. They appear to be a little old, but not worn out
  3. I cleaned everything, so no dust etcetera in the drives
  4. Pressure on the MMC element is set to 1 grams
  5. The records: problem occurs on multiple records, new and old
  6. Lubrication: is removed. As its all plastic parts moving over metal rails, lubrification/grease shouldn't be needed
It feels as if both problems are related. They first occurred at the same time and both problems have to with the drive of the sledge. As said: I've searched in all forum history and found similar problems, but unfortunately no solutions. Can you help me out on this one? I've had a lot of new records, but cannot enjoy them...

Any help is greatly appreciated!

I’m not sure about the issues listed, but I think you still need to add lube to allow free motion even though it is plastic on metal.

I also think the need for lubrication is a must. There is a section in the service manual pointing out how. The cartridge need more than 1 gram to track correctly. The MMC-2 I have from www.tonabnehmerservice.de have a recommended 1.4 gram for best tracking. 

Thanks for the input, but I don't think lubrication is the (main) cause of this. There seems to be some positioning error.

Just to be sure I'll replace the drive belt and see if that does the trick. I just read another topic where it did... I'll keep you posted.

Hi Tsjoechov,

Did you manage to fix your problem. I have a beogram 5005 and the tone arm can be adjusted so that it just (and only just) reaches the edge of the LP. I would like it to go a mm or so further but there is no adjustment left.


The small hook for the carriage wire is about to break off.

Martin

Thank you Martin. That would certainly explain what I'm seeing. However I've double checked and the peg does not appear to be about to break. I've taken a photo to show what I see...

Looks fine, I agree.
Will the excentric not move the set-down point at all?

Martin

Yes it does adjust the setdown point. When the spring is short the setdown is about 4 or 5mm before the record start. At its longest length the setdown is just at the start, but falls of about 1 in 10!

Check that the carriage wire has been fitted correctly;
It has a small knot from factory, that needs to sit in a small cutout along the ridge across the cam wheel it has been fitted around.
