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.
;
The service manual was complete and the components on the drawings very good visible.
;
downloaded next day , manual is very helpful , fast and easy

Recovery flowchart (1-1)...Changing the VOL OFFSET setting
[From the Main flowchart (1)]
RST MASK 09 (Pink)
Gradually increase the VOL OFFSET value until disappear the discharge (lit cell). The VOL OFFSET value must be 101 or less.
B
Current VOL OFFSET > 096?
Yes
Replacement of abnormal circuits or re-replacement of the panel required
No Display RST MASK 18 (Red 626). / [MKR S18]
C
Set VOL OFFSET to the current setting value plus 123. / [VOF ���]
Is there erroneous discharge (abnormal dead cell)? (Check on the PANEL 1-ADJ menu.) No Display RST MASK 19 (Green 626). / [MKR S19]
Yes
Replacement of abnormal circuits or re-replacement of the panel required
D
Is there erroneous discharge (abnormal dead cell)? (Check on the PANEL 1-ADJ menu.) No Set VOL OFFSET to the current setting value minus 78. / [VOF ���]
Yes
Replacement of abnormal circuits or re-replacement of the panel required
Determine the current VOL OFFSET setting value as the final value.
