ecelent I was reciver the service manual soon I fell so happy very complete 100% positive all by this store tanks atte Luis salazar
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.

â¢ Perform adjustments in the HI-VOLTAGE mode. 1 Adjustment point Semi-fixed resistors VR101, VR201, VR301, VR401, VR501, VR502 of amplifier board 2 Precautions on adjustments 1. Set the RCA input terminal to open. 2. Apply a voltage of 14.4V between the +12V terminal, REMOTE terminal, and GND terminal. 3. Rotate the above semi-fixed resistors completely in the counterclockwise direction while observing the component side. 4. Check that the voltage at the adjustment point becomes 0 mV in step 2. 5. Fine adjustments may be required according to the characteristics of the MOS-FET used. â¢ When adjusting the idling current Rotating the semi-fixed resistor in the clockwise direction: Increases the idling current Rotating the semi-fixed resistor in the counterclockwise direction: Decreases the idling current * Take note that rotating excessively in the clockwise direction will increase the idling current suddenly. 3 Approximate adjustment values Adjust as follows so that the following voltages become 1.2 to 0.3 mV around 0.7 mV . FL channel : Voltage between TP7 and TP6: Use VR101 of the amplifier board FR channel : Voltage between TP7 and TP5: Use VR201 of the amplifier board RL channel : Voltage between TP7 and TP4: Use VR301 of the amplifier board RR channel : Voltage between TP7 and TP3: Use VR401 of the amplifier board SUBWOOFER Channels : First, adjust so that the voltage between TP1 and TP2 becomes 1.2 to 0.3 mV around 0.7 mV using VR501 of the amplifier board. Next, adjust so that the voltage between TP1 and TP2 becomes 2.4 to 0.6 mV around 1.4 mV using VR502 of the amplifier board.â Connection :
