A superb deck - I restored mine, you can see the main PCB below.
The faults were as follows, when I decided to operate it in 2003, after having had it in storage for about 15 years:
1. All the rubber belts reeded replacement - from Martin Olsen - Dillen.
2. All the rubber washers had hardened - no replacements available, so I "skinned" the edges during rotation with a Japanese knife, to expose the soft rubber.
3. The blue PSU caps were high ESR - replaced.
4. The Autostop reed switch was faulty - replaced, and I have extra spares if you need.
5. The oxidized trimmer pots were replaced.
Oh yes, and I disassembled the motor completely, replaced the 3 bipolar phase-shift caps on the armature, oiled the shaft with sewing-machine oil, and reassembled the motor.
At this stage it was operating, but pretty poor sound, dark with no definition.
Then I decide to do a full restoration, replacing every electrolytic cap on all PCB's with Pansonic FC and FM. In the signal path, I replaced the ceramic caps with Wima MKS2's, and also resistors with Vishay-Dale metal film CFM-55's.
The sound is superb, and well worth restoring.
