The laser head is from Hitachi (go to my website about the button "CDP-Sercice" to get a photo).
I had the Linn Karik been several times for service. The laser unit was still in perfect condition after cleaning. In most cases the disc motor was poor or failured. The original disc motor comes from two different companies:
1) Mabuchi
2) Matsushita

If your disc motor device from Matsushita, replace it through a device from Mabuchi (higer realibility).

Please note, this isn't easy, because you must remove the pressed turntable (motor pulley) and you need new holes for the Mabuchi Motor (because the screw holes for the motor screws are arranged differently) !!!
The last step is the exactly height adjustment of your turntable (motorpulley)
If necessary, did cut the motor shaft.


If you are not a technician and Linn continued service support of this model, I say also: Send it to Linn.

it sounds like you are right, motor failure because there is lots of noise and disc spinning very fast, disc cannot be read.

Default Karik Turntable Motor Failure

The tray and sled motors are working fine but my turntable motor appears to have died although I haven't stripped it down further yet. My Karik is a II (Ser.4600) and has the HOP-M3 laser. I notice that Donberg have the HOP-M3A mechanism available. Is the M3A compatible with the M3 ?.

HOP-M3A is for serial number 13000 or higher

The HOP-M3A is compatible only electrical to the HOP-M3. But the connectors uses other place - have a look at the photos of both versions on my website - "CDP-Service"
A. Kirschner, individuelle Basslautsprechersysteme
Perhaps it is also possible to install, but I cannot say exactly, because I have it never tested.
If your Motor from Matsushita instead from Mabuchi (check the logo on your motor housing), your observed failure is typical. If the Motor from Donberg's mechanism comes also from Matsushita, don't order it (call and ask the motor brand before ordering). Mabuchi disc motors are not the best choice, but much more better regarded reliability and life time than this one from Matsushita.
If you find a mechanism with Mabuchi Motor, you can order this and exchange the optical pickup with your currently version, if there by the new device the other connector outline.
If you don't find this, the unpleasant work describted about post #3 must be carried out. If you don't find technicians, that can do this, you can mail me (and then perhaps send me your loader for motor exchange).
In this case I started this thread:
Compact Disc Motor and Turntable - Advices for Replace and Motor Service wanted
The mentioned unpleasant work would be a little more easy, if I have a suitable turntable with set screw for exactly height adjustment instead the old "one-way" version for pressing.

P.S. I have heard, Linn Karik was in use 79.000 h by the sound systems of "Queen Elizabeth II" - to read only in German about

I cannot believe this, if a Matsushita disc motor inside
