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.
9. DC Balance / Mono Distortion Adjustment Settings : � Test point : TP3, TP4 (DC Balance) : TP5(Lch), TP6(Rch) (Distortion) � Adjustment location : L801 � Input level : 60dBµV Method : Set to FM 98.0MHz and adjust L801 so that the voltage between TP3 and TP4 is 0V ± 300mV with minimum distortion.
15. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP7(Lch), TP8(Rch) � Input signal : 1kHz (LINE IN) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP7, TP8 becomes 280mV. Record and play back the 1kHz signals and check that the output is �1dB ± 3.0dB.

10. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP7(Lch), TP8(Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000Hz ± 5Hz (FWD) and ± 45Hz (REV) with respect to forward speed. 11. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�300 � Test point : TP7(Lch), TP8(Rch) � Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the 10kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 12. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�300 � Test point :TP7(Lch), TP8(Rch) Method : Play back the 315Hz and 10kHz signals of the test tape and check that the output ratio of the 10kHz signal with respect to that of the 315Hz signal is 0dB ± 3dB. 13. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP7(Lch), TP8(Rch) Method : Play back the test tape and check that the output level of the test point is 280mV ± 3dB. 14. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP7(Lch), TP8(Rch) � Input signal : 1kHz / 10kHz (LINE IN) � Adjustment location : SFR351 (Lch) SFR352 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP7, TP8 becomes 28mV. Record and play back the 1kHz and 10kHz signals and adjust SFRs so that the output of the 10kHz signals becomes 0dB ± 1.0dB with respect to that of the 1kHz signal.
