If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all t

9、he protective devices such as insulation barriers, insulation papers shields are properly installed. 3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.1.1. Leakage Current Cold Check 1. Unplug the AC cord and connect a jumper

10、 between the two prongs on the plug. 2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the readi

11、ng should be between 1M and 5.2M. When the exposed metal does not have a return path to the chassis, the reading must be. Figure 1 1.1.2. Leakage Current Hot Check (See Figure 1) 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5k, 1

12、0 watts resistor, in parallel with a 0.15F capacitor, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1. 3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor. 4. Check each exposed

13、 metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to make the hot checks, lea

14、kage current must not exceed 1/2 milliamp. In case a measurement is out of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer. 5 SA-VK950GC / SA-VK950GS / SA-VK950GCS / SA-VK950GCT 2 service manual

Before Use (For GS/GCS/GCT only) Be sure to disconnect the mains cord before adjusting the voltage selector. Use a minus(-) screwdriver to set the voltage selector (on the rear panel) to the voltag

16、e setting for the area in which the unit will be used. (If the power supply in your area is 117V or 127V, set to the “127V” position.) Note that this unit will be seriously damaged if this setting is not made correctly. (There is no voltage selector for some countries, the correct voltage is already

17、 set.) 1.4. Before Repair and Adjustment Disconnect AC power, discharge Power Supply Capacitors C2254, C2256, C2288, C2289, C2632, C2721, C2725, C2811, C2815, C2817, C5512, C5513, C5514, C5712, C5713, C5715, C5718, C5790, C5805, C5806, C5807, C5914, C5916, C5917, C5929, C5930, C5971 and C5977 throug

18、h a 10, 5W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid overcurrent. Current consumption at AC 110 127V, 50 / 60 Hz QZZCWAT 14.1.1. He

If you wish to readjust the head azimuth, be sure to adjust with adhering the cassette tape closely to the mechanism by pushing the center of cassette tape with your finger. (shown in Fig. 3) 1. Playba

21、ck the azimuth adjustment portion (8 kHz, -20dB) of the test tape (QZZCFM) in the forward play mode. Vary the azimuth adjustment screw until the output of the R-CH (PB OUT-R) are maximized. 2. Perform the same adjustment in the reverse play mode. 3. After the adjustment, apply screwlock (NEJI-LOCK)

22、to the azimuth adjusting screw. Screw-Lock applied on the screw must be more than 180 around screw. 14.1.2. Tape Speed Adjustment (Deck 1/2) 1. Set the tape edit button to “NORMAL” position. 2. Insert the test tape (QZZCWAT) to DECK 2 and playback (FWD side) the middle portion of it. 3. Adjust Motor

23、 VR (DECK 2) for the output value shown below. Adjustment target: 2910 3090 Hz (NORMAL speed) 4. After alignment, assure that the output frequency of the DECK 1 FWD are within 90 Hz of the value of the output frequency of DECK 2 FWD. Fig. 1 14.1.3. Bias Voltage Check 1. Set the unit “AUX” position.

24、2. Insert the Normal blank tape (QZZCRA) into DECK 2 and the unit to “REC” mode (usekey). 3. Measure and make sure that the output is within the standard value.
