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

This Service Manual was exactly what I needed to repair my Philips TV. The purchase was convenient and I received the manual at the same day I paid for it.

NOTES ON SCHEMATIC DIAGRAM
� Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with �Fusible� is a fuse type. � Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means pico-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression �capacitance/withstand voltage� is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type (P.P.): Polypropylene type � Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice. � The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given. 1. In the tuner section, indicates AM indicates FM stereo 2. In the power section, a tape is being played back. � Parts marked with � 1 � ( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
