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!

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.
1. Focus Offset Adjustment a) Connect an oscilloscope between test points (FEl) and (VREF). b) Turn on the main power to the CD player (CD STOP). c) Adjust SFR302 so that the Offset level becomes OmV with reference to VREF. 2. Focus Bias Adjustment a) Connect an oscilloscope to test points (RFO) and (VREF). b) Insert test disc TCD�782 (YEDS-18) and PLAY BACK track No.2. c) Adjust SFl1301 so that the level of RF wave to be Maximum and clear.
3. Tracking Balance Adjustment a) Connect an oscilloscope to test points (TSO)and (VREF). b) PLAY BACK test disc TCD-782 (YEDS-18). c) With F> or<< button pressed, adjust SFR304 so that the wave form on the oscilloscope is vertically symmetrical.
