SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK ON THE SCHEMATIC DIAGRAM AND IN THE PARTS LIST ARE CRITICAL FOR RISK OF FIRE AND ELECTRIC SHOCK. REPLACE THESE COMPONENTS WITH ONKYO PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL. MAKE LEAKAGE-CURRENT OR RESISTANCE MEASUREMENTS TO DETERMINE THAT EXPOSED PARTS ARE ACCEPTABLY INSULATED FROM THE SUPPLY CIRCUIT BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

TX-8011 SERVICE PROCEDURES
1. Replacing the fuse
This symbol located near the fuses indicates that the fuse used is fast operating type. For continued protection against fire hazard, replace with same type fuse. For fuse rating refer to the marking adjacent to the symbol. Ce symbole indique que le fusible utlise est a rapide. Pour une protection permanente, n'untiliser que fusibles de meme type. Ce darnier est la qu le present symbol est appse. CIRCUIT NO. F901 PART NO. 252163 DESCRIPTION 4A-UL/T-237,Fuse
2. To initialize the unit
This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions to operate abnormally. To perform a result, please follow the procedure below. 1.Press and hold down the TAPE 1 button, then press the DIRECT TUNING button. 2.After "CLEAR" is displayed, the preset memory stored in the memory, are initialized and will return to the factory setting.
3. Safety-check out
(Only U.S.A. model) After correcting the original service problem, perform the following safety check before releasing the set to the customer. Connect the insulating-resistance tester between the plug of power supply cord and screw on the back panel. Specifications: 3.3Mohm 10% at 500V.
4. Memory Preservation
This unit does not require memory preserv ation batteries. A built-in memory power back-up system preserv es the contents of the memory during po wer f ailures and even when the unit is unplugged. The unit must be plugged in order to char ge the back-up system. The memory preserv ation period after the unit has been unplugged v aries depending on climate and placement of the unit. On the average, memory contents are protected over a period of a fe w weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate.

TX-8011 ADJUSTMENT AND CONFIRMATION PROCEDURES 1
Idling current adjustment Before Idling adjustment, turn the trimming resistors R533 and R534 to counter clockwise. Connect the DC voltmeter to terminals P521 and P522. After turn POWER to ON, adjust the trimming resistors R533 and R534 so that the reading of voltmeter becomes 2.0 mV. After adjustment, attach the top cover. Confirm the voltage of points above after about five minutes. When less than 7.0 mV, readjust the resistors above so that the voltage becomes 7.0 mV. When 7.0 mV to 9.0 mV, you are not necessary to adjust. When more than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV.

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 DIRECT TUNING button. After "TEST- " on the FL tube light on, press TAPE 1 button to set the unit to "TEST-1 00". Apply DC 1.5 to 3V to CD terminal with no load. Confirm that the speaker relay turns OFF. Apply DC -1.5 to -3V to CD terminal with no load. Confirm that the speaker relay turns OFF. Caution: Don't apply DC voltage more than 1 sec..

3. Confirmation of Current detection circuit Set the unit to "TEST-1 00". Connect the differentiating circuit and apply the 200Hz square signal to CD terminal of each channel. Adjust the attenuator or Volume so that the output level becomes 35V p-p. Confirm that the speaker relay does not turn OFF when a 2.0 ohm load is connected. Confirm that "Protect" indicator lights on when a 0.5 ohm load is connected. Caution:Don't continue more than 3 seconds.
