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.

6.3 METHOD FOR REPLACING THE SERVICE PANEL ASSY
A
When the Panel Assy is replaced with one for service, the following adjustments are required:
Adjustments of Vofs voltage and Vyprst voltage
Enter the reference adjustment values for the Vofs voltage and Vyprst voltage that are written on the label attached to the panel for service. Note: Enter the values, using an RS-232C command or the Factory Menu.
AWU���� Vofs = 35V Vyprst = 270V Hour Meter Space H (Rear of the Panel)
B
AWU���� Vofs = 35V Vyprst = 270V Hour Meter 1520 H Write in the value for the hour meter when the Panel is replaced (ex. 1520H).
Using an RS-232C command Enter a "PFY" command with Factory mode ON. Convert the adjustment voltage values written on the label attached at the rear of the Panel to an input command, referring to the conversion chart. (See the next page.) � Reference adjustment of the Vofs voltage: Ex. "Vofs = 35" � (Check the conversion chart.) Enter "VOF112." � Reference adjustment of the Vyprst voltage: Ex. 50-inch "Vyprst = 270 V" � (Check the conversion chart.) Enter "VRP055." (Note that the conversion charts for 50-inch and 43-inch Panels are different.) Using the Factory Menu

Select the main item "PANEL FACT." by pressing the MUTE key then enter Panel Factory mode by pressing the SET key. Using the 5/� keys, select "PANEL-1 ADJ" then press the SET key to enter the next lower nested layer. Select "VOL-OFFSET" or "VOL RST P" then enter a command value converted from the voltage value, using the 2/3 keys.
Clearing data on various histories of the Panel, such as those on the hour meter
� It is necessary to clear the data on the hour meter, etc. to match them to the actual driving hours of the Panel. � It is also necessary to clear the data on SD and PD, because the accumulated power-on time when a shutdown or powerdown occurred is recorded. Note: Clear the values, using an RS-232C command or the Factory Menu. There are two types of hour meters. Do not take the MR hour meter for the hour meter. Using an RS-232C command To acquire the accumulated power-on time of the product itself, use the "GS2" RS-232C command. 1 To clear the data on the hour meter (for the Panel) : CHM 2 To clear the data on the pulse meter : CPM 3 To clear the data on the SD history : CSD 4 To clear the data on the PD history : CPD

Using the Factory Menu See "7.1.7 HOW TO CLEAR HISTORY DATA."
