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.

Increase the MAT CONT adjustment value of OFFSET-RGB1 by 3. OFFSET mode: Select RGB 1 mode with the top and bottom keys. MAT CONT : "1" key Increase the adjustment value by 3 with the right and left keys. Increase the MAT BRIGHT adjustment value of OFFSET-RGB1 by 2. OFFSET mode: Select RGB 1 mode with the top and bottom keys. MAT BRIGHT : "2" key Increase the adjustment value by 2 with the right and left keys. Turn the ACL SW setting to ON. INITIALIZE mode ACL SW : "3" key Select ON with the right and left keys. Input a RGB (PC) signal to the INPUT1 or INPUT2. Use a signal consisting of the luminance signal only, such as a ramp signal or STEP signal, whose black level (0IRE) and gradation can be checked. � Recommended signal: VESA VGA@60Hz

Set the unit to Standby mode then to Factory mode. MENU � SET � POWER ON Take a trigger of the oscilloscope with HD_PLL (3.3Vp-p) of K4805. Measure the signal waveform of the Green signal at K4603, and measure the black level (0IRE) and amplitude. AD R LOW adjustment Measure the black level (0IRE) of the Red signal at K4602, and adjust the level of AD R LOW so that its black level (0IRE) becomes the same as that of the Green signal measured in step 9. Tolerance: ± 0.05V OFFSET mode: Select RGB 1 mode with the top and bottom keys. AD R LOW : "9" key Adjust with the right and left keys.

AD R HIGH adjustment Measure the signal amplitude of the Red signal at K4602, and adjust the level of AD R HIGH so that its signal amplitude becomes the same as that of the Green signal measured in step 9. Tolerance: ± 0.05V OFFSET mode: Select RGB 1 mode with the top and bottom keys. AD R HIGH : "6" key Adjust with the right and left keys.
