This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.

Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!

6.1. Grounding for electrostatic breakdown prevention
Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electricity in the working environment. Proceed servicing works under the working environment where grounding works is completed.
6.1.1. Workable grounding
1. Put a conductive materials (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet.
6.1.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity from your body.
6.1.3. Handling of optical pickup
1. To keep the good quality of the optical pickup maintenance parts during transportation and before installatio,. the both ends of the laser diode are short-circuited. After replacing the parts with new ones, remove the short circuit according to the correct procedure. (See this Technical Guide.) 2. Do not use a tester to check the laser diode for the optical pickup. Failure to do so will damage the laser diode due to the power supply in the tester. 6.2. Handling Precautions for Traverse Unit (Optical Pickup) 1. Do not give a considerable shock to the traverse unit (optical pickup) as it has an extremely high-precise structure. 2. When replacing the optical pickup, install the flexible cable and cut its short land with a nipper. See the optical pickup replacement
