I have now gotten around working on both machines.
I have placed washers under the rubber suspension on the CD 7000, but they might not be thick or high enough, because I still hear the ticking noise. However, examining the operation of the drive with the lid off, I noticed that CDs are not necessarily centered properly, meaning that the hole in the CD is not exactly in the middle. This causes the pickup to constantly move forwards and backwards focusing on the “track”. I just have a feeling that the noise that I’m hearing is more prominent on these “uneven” discs. Nevertheless I will try to lift the suspension a bit more, when I find something suitable to place under the suspension rubber.
Regarding the Beocord 7000. It was a fairly easy operation. I used a bit of isolation from a wire, which was a tight fit, so that it will hopefully stay on the little plastic pin. I could verify visually that the brake was now fully released, when the heads were engaged. By the way, there was a ticking sound when playing in the reverse direction, that was caused be the brake as well. This has now also gone.
Thank you again for your help to all 3 of you, who came with good tips.
Best regards
Henrik
