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!

Thank you very much. the Instruction corresponds to my expectations. Sent it in time. I don't regret that paid money.
Alignment and Adjustments
4-3-3 High Voltage Check
4. Input a black and white signal.
CAUTION: There is no high voltage adjustment on this chassis. The B+ power supply must be set to +125 volts (Full color bar input and normal picture level).
5. Fully demagnetize the receiver by applying an external degaussing coil. 6. Turn the CONTRAST and BRIGHTNESS controls to maximum. 7. Loosen the clamp screw holding the yoke. Slide the yoke backward or forward to provide vertical green belt. (Fig. 4-2). 8. Tighten the convergence yoke. 9. Slowly move the deflection yoke forward, and adjust for the best overall green screen. 10. Temporarily tighten the deflection yoke.
1. Connect a digital voltmeter to the second anode of the picture tube. 2. Turn on the TV. Set the Brightness and Contrast controls to minimum (zero beam current). 3. The high voltage should not exceed 27.5KV. 4. Adjust the Brightness and contrast controls to both extremes. Ensure that the high voltage does not exceed 27.5KV under any conditions.
4-3-4 FOCUS Adjustment
1. Input a black and white signal. 2. Adjust the tuning control for the clearest picture. 3. Adjust the FOCUS control for well defined scanning lines in the center area of the screen. 11. Produce blue and red rasters by adjusting the low-light controls. Check for good purity in each field. 12. Tighten the deflection yoke.
4-3-5 Cathode Voltage Adjustment (Screen Adjustment)
1. Enter the FACTORY mode. 2. Select the G2-ADJUST. 3. Adjust the screen VR(on the FBT) so that �SCREEN ADJUST : NG(Red or Blue)� becomes �SCREEN ADJUST : OK�. When the color of �SCREEN ADJUST� is red, the cathode voltage is low and when blue, it is high.
4-3-6 Purity Adjustment
1. Warm up the receiver for at least 20 minutes. 2. Plug in the CRT deflection yoke and tighten the clamp screw. 3. Plug the convergence yoke into the CRT and set in as shown in Fig. 4-1.
