Hi Mark,
Some progress in understanding following your last suggestions.
First I observed the lowering of the arm (“Descent” video, sorry for the quality). I seems to descend deep enough.
Then I checked the tracking force with an electronic gauge (bought new for the testings) and noticed some oddities:
- After the arm has finished it’s lowering, the tracking force is not sufficient. But if I give a little tap on the turntable, the tracking force meets the required one (“tracking force” video).
- At the end of a disc with spaced grooves, the arm skips. But if I blow strongly on the arm, it moves again to the end and goes in parking position (blow video).
- If I blow or tap at the beginnig of this disk, the arm does not skip on spaced grooves.
Could there be something that ‘holds back’ the arm during its descent, preventing it from pressing on the disc with the correct tracking force?
Blowing on the arm at the beginning of each disc is not a very beo-ish and practical practice!!
Kind regards,

Hi Mark,
I’m 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 “tapping” 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 skips… 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.

Dear Emma,
Your pre-amp seems to be the same as one sold by Sounds Heavenly.
If yes, you might ask Steve’s help to solve your problem.
A few questions to help your investigations:
- I noticed on your picture that the pre-amp’s LED is orange, isn’t it a warning (check the user guide)?
- Do your speaker work with another source plugged in the RCA inputs?
- Did you select the RCA input with the input selector of your speaker (it does not seem to automatic)?
- Looking at the YU5 user guide, this speaker has optical inputs that I don’t see on your picture. Are you sure yours is a YU5?
- Is the turntable’s cartridge correctly plugged on the reading arm?
If you have another product with RCA inputs, you could connect the pre-amp out to this product.
Kind regards,
Yann.

Thank you Mark,
I’ll try to make the adjustment, it seems to be rather tricky.

Bonjour et merci pour l’info.
J’ai trouvé le site d’ADE Frangeul, ils parlent d’une agence à Craon. C’est de celle-ci que tu parles?
Pour un resto, why not à l’occasion d’un passage à Craon.
Je te tiens au courant.
A+,

Hi,
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 13′ 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 don’t know how to remove it from the rails and would avoid to break anything.
May someone explain the process?
Kind regards,
Yann.

You are right, Stephen, I use the beta app through TestFlight which allows to send screenshots to the team.
I did not imagine they would send this un-functional version on the release channel.

Stephen,
On an iPhone:
- Take a screenshot of the phone with the message.
- When tapping “OK” , on the 1st line of the list which appears, there is “Share the Beta Evaluation”.
- A new window will open with the screenshot and a space for your remarks.
Regards,
Yann.

Update:
- The stylus is new (Soundsmith SMMC20 EN)
- The lamp of the tracking arm and the photo control are glowing.
I tried to adjust the tracking arm’s height at 19,5mm as explained in the service manual.
I noticed that a small tap on the tracking arm starts the playback (I can see the , as if there is a focus issue with the sensor that is solved by the tap. But it has to be done for each disc and I fear that it will harm the tracking arm.
What could I do to go further?
Kind regards,

Hello Beoworlders,
The belt of the arm carriage of my Beogram 6006 (type 5625, 1984, with linear motor) was broken and I replaced it.
Unfortunately, the detection arm was damaged during the disassembly 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 attached 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.

Just FYI 7.01 is already being tested and fixes a lot of other problems. Hopefully it addresses these issues as well
Unfortunately not (version 7.0.1.250820368)
