A great copy of the manual, and the only one I could find anywhere on the net! The circuit diagrams are easily readable, all component values marked and easy to see. A highly appreciated download!
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.
