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.

6. ADJUSTMENT
CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
� Note : The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mechanism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if the PU unit must be changed, the grating should be checked using the procedure below.
� Purpose : To check that the grating is within an acceptable range when the PU unit is changed. � Symptoms of Mal-adjustment : If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform track search operations, or taking a long time for track searching. � Method : � Measuring Equipment � Measuring Points � Disc � Mode
� Oscilloscope, Two L.P.F. � E, F, REFOUT � ABEX TCD-784 � TEST MODE

� Checking Procedure 1. In test mode, load the disc and switch the 5V regulator on. 2. Using the TRK+ and TRK- buttons, move the PU unit to the innermost track. 3. Press key F9 to close focus, the display should read "91". Press key F8 to implement the tracking balance adjustment the display should now read "81". Press key F9 4 times. The display will change, returning to "81" on the fourth press. 4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase difference is within 75° . Refer to the photographs supplied to determine the phase angle. 5. If the phase difference is determined to be greater than 75° try changing the PU unit to see if there is any improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the mechanism should be judged to be at fault. � Note Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the average angle. � Hint Reloading the disc changes the clamp position and may decrease the "wobble".
