ELECTRICAL ADJUSTMENT

Bias Adjustment

Note : The Bias adjustment should be performed only if any of

Q109 and Q110 for RV104, Q209 and Q210 for RV204, Q309 and Q310 for R V304, and Q409 and Q410 for RV404 are replaced.

Procedure:

1. Rotate variable resistors RV104 (FRONT L-CH), RV204 (FRONT R-CH), RV304 (REAR L-CH) and RV404 (REAR R-CH) full clockwise as seen from the pattern side to minimize the bias current.

2. The input signal is with no signal.

3. Connect the stabilized power supply between B+ and REM terminals and gradually increase the voltage to 14.4 V while checking for any abnormal current.

4. Adjust R V104 (FRONT L-CH), R V204 (FR ONT R-CH), R V304 (REAR L-CH) and RV404 (REAR R-CH) so that the digital voltmeter connected between the respective test points reads 6±1 mV.

RV Ref. No. Test points

RV104 TP11 and TP12 RV204 TP21 and TP22 RV304 TP31 and TP32 RV404 TP41 and TP42

5. After this adjustment, verify that the current value of the stabilized power supply is 1.4 to 1.8 A.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

for schematic diagram: Note:

• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

•%: indicates tolerance.

• 2 : nonflammable resistor.

• C : panel designation.

Note:

The components identified by mark 0 or dotted line with mark 0 are criti- cal for safety. Replace only with part number specified.

• A : B+ Line.

• B : B– Line.

• H : adjustment for repair.

• Power voltage is dc 14.4V and fed with regulated dc power supply from +12V and REM terminals.

•Voltage and waveform are dc with respect to ground under no-signal condition.

•Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

•Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.

• Signal path. F : AUDIO
