THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR
;
Very Good! All the diagram are easy to read, and its complete.
;
This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!

1. Clock Frequency Check Settings: � Test point: TP2 (CLK IC771 pin30) Method: Set to AM 1710kHz and check that the test point becomes 2160kHz±45Hz. 2. AM VT Check Settings: � Test point: TP1 (VT) Method: Set to AM 1710kHz and check that the test point is less than 8.5V. Then set to AM 530kHz and check that the test point is more than 0.6V. 3. AM IF Adjustment Settings: � Test point: TP5, TP6 L772 .............................................. 450kHz 4. AM Tracking Adjustment Settings: � Test point: TP5, TP6 � Adjustment location: L981 (1/3) Method: Set to AM 999kHz and adjust L981 so that the test point becomes maximum. 5. FM VT Check Settings: � Test point: TP1 (VT) Method: Set to FM 87.5MHz, 108.0MHz and check that the test point is more than 0.5V (87.5MHz) and less than 8.0V (108.0MHz). 6. DC Balance/Mono Distortion Adjustment Settings: � Test point: TP3, TP4 � Adjustment location: L771 � Input level: 60dB Method: Set to FM 98.0MHz and adjust L771 so that the voltage between TP3 and TP4 becomes 0V±0.04V. Next, check that the distortion is less than 1.3%.
