 ;
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.
4-1-3. Video Tracking Check and Adjustment
Adjustment Tape Entrance Side 12. Change the Mode Setting (1) Press the SET button to cancel the SWITCHING PB mode. (2) Turn the search dial while pressing the JOG button so that the �Full PB� is indicated, and press the SET button. n After that, the overlap portion appears on the RF waveform. 13. Adjust the Tracking at Tape Entrance Side (1) Play back the SR2-1/P (00:00 to 15:00). (2) Push S100 switch on the SS-83 board more than 1 sec. so that the tracking VR becomes to be effective. LED: Check that D112 lights up. (3) Turn RV100 on the SS-83 board clockwise and adjust the center portion of the RF envelope waveform makes 80% of the maximum output level. (4) Loosen the height adjustment nut of TG-2, and turn the upper flange so that the tape does not in contact with the upper flange of TG-2. (5) Turn the height adjustment nut of TG-1 so that the overlap portion of the entrance side of the RF envelope waveform makes flat. (Fig. 1) If the waveform does not make flat, perform the check described below. 1 Clean the drum lead with a bamboo stick. (Refer to Section 5-2-4 of the maintenance manual part 1.) 2 Press down the tape by bamboo stick very lightly and check that the tape is running along the drum lead. (6) Turn the height adjustment nut of TG-1 clockwise 30d more from the state of the step (5). n Turning the height adjustment nut causes the waveform of the overlap portion to be not flat. (7) Turn the height adjustment nut of TG-2 to clockwise so that the upper flange contacts the tape. � Continued on the next page. �
