Hello Beoworlders,
The belt of the arm carriage of my Beogram 6006 (type 5625, 1984,ย with linear motor) was broken and I replaced it.
Unfortunately, the detection arm was damaged during the disassemblyย and I had to fix it by gluing the plastic holder where the arm is screwed on the carriage.
I managed to have it horizontal.
Now, when I play a record, the carriage moves to the beginning of the record (it also makes a complete cycle with speed change if no record is present) and the stylus descends. So it seems that the detection system is OK.
But when the disc reading starts, the arm does not move and the stylus jumps as if with a scratched disc (see attahed video). Same problem if I move the arm in the middle of the record.
What could it be and what can I check?
Thanks by advance,
Yann.

I tried to adjust the tracking armโs height at 19,5mm as explained in the service manual.
I noticed that a small tap on the tracking arm starts the playback, as if there is a focus issue with the sensor.
What could I do to go further?
Kind regards,
Yann.

I would check with it open and lowering the arm to the right of the platter. It should move freely the 1/2 inch to the sensor arm. Sometimes the optical shutter is sticking or has be rotated so it hits its stop prematurely.

Thanks for your reply.
Iโve ordered a new belt from Beoparts and await for it.
Iโll take back the TT to the bench when Iโll recieve it and let you know.
Kind regards,
Yann.
Location: Brittany, FranceMy B&O Icons:8 September 2025 at 10:45 #69470FOUNDER MemberHi,
Attached a new video with the issue and what happens when I tap slightly the chassis.
You can also note the carriage motor on the right of the video.
It stops moving at 13โฒ of the video and goes back after the tap. First rather fast, then by steps following the move of the reading arm.
Same issue with my 3 cartidges, so I doubt that the stylus are involved.
Tracking arm set at 19,5 mm from the aluminium part of the platter and tracking weight at 1,2 g.
So I wonder if something is mis-aligned in the carriage, but I donโt know how to remove it from the rails and would avoid to break anything.
May someone explain the process?
Kind regards,
Yann.

Iโll try to make the adjustment, it seems to be rather tricky.

Iโm rather worried to touch this setting.
First the screw is not easy to reach, second it has never been touched since factory and everything was OK until my desastrous attempt to bring the turntable to service position: I forgot to push the chassis to the right and of course, the arms suffered:
- The detection arm broke. I glued it and I think that the problem is solved as the beginning and the end of the disk are detected.
- I did not notice anything on the reading arm, but obviously something went wrong.
Here are the checks and settings already done:
- The platter is flush with the aluminium panel,
- The arms are 23 mm to the aluminium part of the platter,
- Tracking force is 1,2 g, measured with an electronic gauge.
In some cases, the reading of the disk from the beginning works well and if I do not cue to another song it goes to the end without difficulty. In other cases not.
I already posted a video showing that โtappingโ on the chassis makes the arm move again. Today I noticed that blowing a bit hard near the cartridge has the same effect.
The end of the disk is more problematic. I noticed that when the grooves of the disk are more widely spaced, the cantilever goes far to the left but the arm does not move, so the stylus skipsโฆ until I blow. Then the arm moves again, first to the center, then back to parking position.
Could it be something in the lowering of the arm which in some cases does not go down far enough? And what could I check?
Kind regards,
Yann.
