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!

TX-SR803/E ADJUSTMENT AND CONFIRMATION PROCEDURES 1
Idling current adjustment Before Idling current adjustment, turn the trimming resistors R6040 to R6046 to counter-clockwise. Connect the DC voltmeter at the sockets P6080 to P6086 via the carbon resistors 100 ohm 1/4W.
DC voltmeter 100 ohm 1/4watts Jig terminal Test point ID+ ID-
After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of voltmeter becomes 2.5 mV. (Front and center channels) Adjust the trimming resistors R6043, R6044, R6045 and R6046 so that the reading of voltmeter becomes 1.5 mV. (Surround and surround back channels) After adjustment, attach the top cover. Confirm the voltage of points above after about five minutes. Front and center channels When less than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV. When 9.0 mV to 11.0 mV, you are not necessary to adjust. When more than 11.0 mV, readjust the resistors above so that the voltage becomes 11.0 mV. Surround and surround back channels When less than 6.0 mV, readjust the resistors above so that the voltage becomes 6.0 mV. When 6.0 mV to 8.0 mV, you are not necessary to adjust. When more than 6.0 mV, readjust the resistors above so that the voltage becomes 8.0 mV. Note: No load and No signal

Confirmation of protection circuit 1. Confirmation of operation of speaker relay Confirm that the speaker relays turn ON approximate 5 seconds after the power switch is turned ON. Confirm that the speaker relays turn OFF immediately after the power switch is turned OFF. 2. Confirmation of DC detection circuit Press and hold down CD button, then press STANDBY/ON button to set the unit to "Test- 1". After "Test- 1" on the FL tube light on, press DVD button to set the unit to "Test- 1-00". Apply DC 1.5 to 3.5V to the MULTI-CH INPUT terminal with no load. Confirm that the speaker relay turns OFF. Apply DC -1.5 to -3.5 V to the MULTI-CH INPUT terminal with no load. Confirm that the speaker relay turns OFF. Caution: Don't apply DC voltage more than 1 sec..
