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.

a) Connect DC power supply to battery connector on the handset unit. b) Turn the DC power supply on while pressing � � � and � # � keys, and keep pressing the keys continuously for approximate 2 seconds. c) Release keys when entering TEST mode 1 with TALK LED lighting and beep.
Alignment Procedure
Step Remarks Press the 4 key to enter the TEST Mode 4. Connect the RF Signal SG: 1mV L615 Generator to the RF test point on the handset MAIN PCB. Make sure that (�47dBm) (Discriminator the frequency is 926.997467 MHz. No modulation Voltage) Connect the DC Voltmeter to the AF Terminal of RT603. Adjust L615 to indicate DC 0.85 V. SG: 1mV (�47dBm) 1 kHz ±8kHz Deviation SG: �6.0 dBµV (�113dBm) No modulation RT604 (RX AF Voltage) RT603 (SQ Point) Connect the RF Signal Generator to the RF test point on the handset MAIN PCB. Make sure that the frequency is 926.997467 MHz. Connect the AC Voltmeter across a 150-ohms dummy to the SP Connector. Adjust RT604 for a 113mV (-19dBV) reading on the AC Voltmeter. Press the 5 key to enter the TEST Mode 5. Make sure that the frequency of RF SG output is 926.997467 MHz. Adjust RT603 to turn to the point where the indication is just vibrated. Preset to Adjustment
