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.
;
Complete manual, the good quality of reproduction allows enlarged print-out of the schematic diagram in the size it probably had in the original print edition and which is necessary for practical use.
;
The service manual was complete and the components on the drawings very good visible.
