Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

Received a quick response, material was exactly what it was supposed to be. The service did everything I expected it to do. would use service again.

Detailed SONY CFD980 Service Manual at an easy to find one stop shopping. Make my radio hobby technically interesting. Thanks.

Excellent service from Owner-Manuals.com, good prices and quick turn around. The supplied PDF was good enough quality to be enlarged sufficiently to read component values.

Very complete shop manual. It contains everything needed to troubleshoot bascially any problem. Instructions, diagrams, schmeatics, illustrations... it's all there. Highly recommended!
Precautions during Servicing
A. Parts identified by the ( # ) symbol are critical for safety. Replace only with part number specified. B. In addition to safety, other parts and assemblies are specified for conformance with regulations applying to spurious radiation. These must also be replaced only with specified replacements. Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc. C. Use specified internal wiring. Note especially: 1) Wires covered with PVC tubing 2) Double insulated wires 3) High voltage leads D. Use specified insulating materials for hazardous live parts. Note especially: 1) Insulation Tape 2) PVC tubing 3) Spacers 4) Insulators for transistors. E. When replacing AC primary side components (transformers, power cord, etc.), wrap ends of wires securely about the terminals before soldering. F. Observe that the wires do not contact heat producing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.) G. Check that replaced wires do not contact sharp edged or pointed parts. H. When a power cord has been replaced, check that 5~6 kg of force in any direction will not loosen it. I. Also check areas surrounding repaired locations. J. Use care that foreign objects (screws, solder droplets, etc.) do not remain inside the set. K. Crimp type wire connector The power transformer uses crimp type connectors which connect the power cord and the primary side of the transformer. When replacing the transformer, follow these steps carefully and precisely to prevent shock hazards. Replacement procedure 1) Remove the old connector by cutting the wires at a point close to the connector. Important: Do not re-use a connector (discard it). 2) Strip about 15 mm of the insulation from the ends of the wires. If the wires are stranded, twist the strands to avoid frayed conductors.
3) Align the lengths of the wires to be connected. Insert the wires fully into the connector. 4) Use the crimping tool to crimp the metal sleeve at the center position. Be sure to crimp fully to the complete closure of the tool. L. When connecting or disconnecting the internal connectors, first, disconnect the AC plug from the AC supply outlet.
