Great Manual. This manual is available no where else. It was exactly what I was looking for.

The TEAC A-1500's Service Manual was instrumental in reviving this classic reel-to-reel. Not only does it have the schematics, exploded parts diagram and parts list, it also provided mechanical adjustment information that approximate factory default settings.

This service manual was determinant to enable to fix my Alpine Amplifier. I am pleased with my purchase. For a 5 star rating I would like to see a higher resolution scan of the printed circuit board lay-out because the gray scale grafics was dificult to see. Also some schematic diagrams were scanned at a slight angle. Never the less, it had all information I needed to troubleshoot and service my equipment.
