For U model “CAUTION” “F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE.” For C model CAUTION F1: REPLACE WITH SAME TYPE 6A, 125V FUSE. ATTENTION F1: UTILISER UN FUSIBLE DE RECHANGE DE MÉME TYPE DE 6A, 125V. G Leakage current must not exceed 0.5mA. G Be sure to test for leakage with the AC plug in both polarities. I TO SERVICE PERSONNEL WARNING: CHEMICAL CONTENT NOTICE! The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA- SON WHATSOEVER! Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder. Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair work. • Sn + Ag + Cu (tin + silver + copper) • Sn + Cu (tin + copper) • Sn + Zn + Bi (tin + zinc + bismuth) Caution: As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead solder, be sure to use a soldering iron suitable to each solder.

Removal of Front Grille Ass’y * The front grille ass’y is fixed to the cabinet with dow- els at 5 locations. As a flatblade screwdriver is used for removal, use special care not to cause damage to the cabinet ass’y. a. Using the flatblade screwdriver inserted in the gap be- tween the front grille ass’y and the cabinet ass’y (bot- tom side first), push up the front grille ass’y. (Fig. 1) b. Remove the front grille ass’y by lifting a metalblade up. (Fig. 1) * When installing the front grille ass’y, apply quick-dry- ing bond or the like to dowels and then fit them into dowel holes for secure installation. (The front grille ass’y will come off easily if its dowels are fitted into dowel holes without applying quickdrying bond or the like.) 2. Removal of Driver a. Remove 4 screws (1)and then remove the driver. (Fig. 1) b. Disconnect the connector connected to the terminal of the driver.

(Fig. 1) 4) Connect the oscilloscope CH2 input to the red side of the connector cable, which is connected with the load resistor. At this time, the GND terminal of CH2 must be left unconnected. V: 20 V/div H: 2 msec/div DC range 1 : 1 probe G Confirmation of power amplifier operation For the power amplifier which has been repaired, it is absolutely necessary to confirm that a correct waveform is obtained at points indicated by A and B in the schematic diagram according to the following procedure. Setting 1) Set the signal generator to the sine wave, 100 Hz and minimum output level settings. 2) Set the volume of the main unit to the minimum po- sition. 3) Turn on the power to the main unit. 4) Adjust the output level of the signal generator and the volume of the main unit so that the output level observed at oscilloscope CH2 is 26 Vp-p to 28 Vp-p. Waveform observation With the settings made as described above, observe the waveform obtained at CH1 for judgment. Point A (Cathode of D29/D30) V: 20 V/div H: 2 msec/div DC range 1 : 1 probe Point B (Anode of D27/D28) G Idling adjustment To stabilize operation of the amplifier, turn ON the power with no input signal and wait for 2 to 3 minutes in non loaded condition before the adjustment. Confirm that the voltage across the terminals TP1 and TP2 is 20 mV to 350 mV. If it exceeds 350 mV, open (cut off) R136. Attention: If the idling current exceeds 350 mV after a power amplifier repair, check for a defective component before cutting the resistor.

(Fig. 2) 3) Connect the output signal from the signal generator to the INPUT 2 / L/MONO terminal of the main unit. 4) Set the signal generator for the sine wave of 100 Hz, 8 mV. 5) Turn on the “POWER ON/OFF” key located on the rear panel. 2) Turn on the “STANDBY/ON” key. The status indicator lights up (green) and its color changes to red after 2 to 8 seconds. 3) Turn off the “STANDBY/ON” key. The status indicator goes off. 5) Turn on the “STANDBY/ON” key. The status indicator lights up (green) and its color remains unchanged even after time have elapsed. 6) Turn off the “STANDBY/ON” key. The status indicator goes off. Confirmation 1) Set the “AUTO STANDBY” key to the LOW posi- tion. 4) Set the “AUTO STANDBY” key to the HIGH posi- tion. After confirmation 1) Turn off the “POWER ON/OFF” key. 2) Disconnect the 10 k-ohms resistor connected to both ends of R45.
