Alte gescannte Servicepläne sind oft doch etwas undeutlich . Stromlaufpläne werden auf mehrere DIN A4 Seiten aufgeteilt. Alles ziemlich umständlich und zeitaufwendig. Aber mit etwas Mühe geht alles.
Great item, high resolution, detailed, very easy to work with.
fast delevery of the manual and very complete manual, now my Akai works again, will buy again, thanks.
Tartalma megfelelő. Szebb kivitelű is lehetne a scannelés.
I never been disappointed in my dealings with owners-manuals.com
DTR-7.3 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. After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of voltmeter becomes 11 mV. (Front and center channels) Adjust the trimming resistors R6043, R6044, R6045 and R6046 so that the reading of voltmeter becomes 4.5 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 16.5 mV, readjust the resistors above so that the voltage becomes 16.5 mV. When 16.5 mV to 18.5 mV, you are not necessary to adjust. When more than 18.5 mV, readjust the resistors above so that the voltage becomes 18.5 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 and DISPLAY buttons to set the unit to "Test-1" mode. After "Test-1" on the FL tube light on, press VIDEO 1 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..
