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!

PURITY ADJUSTMENT
No. Adjusting point 1 PURITY ADJ. Adjusting procedure/conditions 1. Receive the GREEN-ONLY signal. Adjust the beam current to about 500 µA. 2. Degauss the CRT enough with the degausing coil. Note: Follow the Job Instruction Sheet to adjust the magnetic field. Vertical Bv : +0.030 mT (0.30 gauss) Horizontal Bh: +0.020 mT (0.20 gauss) (See page 12.) 3. Maintain the purity magnet at the zero magnetic field and keep the static convergence roughly adjusted. 4. Observe the points a, b as shown in Fig. 4-1 through the microscope. Adjust the landing to the rank A requirements. 5. Orient the raster rotation to 0 eastward. 6. Tighten up the deflection coil screws. » Tightening torque: 108 ± 20 N (11 ± 2 kgf) 7. Make sure the CRT corners landing meet the A rank requirements. If not, stick the magnet sheet to correct it. Note: This adjustment must be done after warming up the unit for 30 minutes or longer with a beam current over 500 µA. Note: Set the service mode by JA122 & JA124 (short) then press factory process R/C RGB key to change to RGB mono colour mode. * For the following colours press R/C RGB key to change.
