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!
VCC3, VCC5 voltage check PCB-LA � Voltage supply CP151 = 5.0 ± 0.05 V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 ± 0.05 V to CP150. (2) Make sure VCC3 (CP160) is 3.3 ± 0.1 V and VCC5 (CP152) is 5.0 ± 0.15 V.
VCC2 adjustment and VCC7, VCC8, VEE2 voltage check � Voltage supply VCL0(CP101)=5.0±0.05V. (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Apply 5.0 V ± 0.05 V to VCL0 and adjust VR100 so that VCC2 will be 5.0 ± 0.02 V. Notes: � VCC7 = 7.3 ~ 8.3 [V], VCC8 = 12.0 ~ 14.0 [V] � VEE2 = �12.3 ~ �16.7 [V] In addition, disconnect the power and make sure all output voltages are 0 V.
VCO free run frequency adjustment � Voltage supply VCC2=5 V ± 0.05 (V) (CP181). VCC8 = 13.5 ± 0.05 (V) (CP180). VEE2 = �15.0 ± 0.05 (V) (CP182). Connect CP705 (CSY) and CP700 (GNP). (You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.) (1) Monitoring CP710 (HDB) with a frequency counter, adjust VR720 so that the frequency will be 15.734 ± 0.1 [KHz]. Notes: � Disconnect CP705 and CP700, then connect PCB-LA and make sure CP705 (CSY) and CP710 (HDB) are synchronized. � Keep room temperature at 20 ± 10°C. QV-770
