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.

2.Removing the Front Protection Panel (Fig. 3, Fig. 4)
1) Remove all screws 2 and 4 inside the front case. Be careful not to remove screws B (two at the bottom) and screws C (three at the top) because they are used for securing the aluminum sash. 2) Remove all panel shields 1 and 3 and panel holders 2 and 4. 3) Remove and replace the front protection panel. 4) Attach the protection panel by attaching to the bottom left side first, and then attach the front case assembly in the reverse procedure of the above. When securing the front case to the unit, attach the two bosses D (one each on the two edges of the top) as a guide so that the boss at the center A passes through the hole on the rear case. Note) When attaching the panel shield and panel holder after replacing the protection panel, the panel shield may deform when tightening the screws 3 as shown in Fig. 4. If it deforms, untighten screws 3 slightly and tighten until just before it starts to bend.
