Adjust VR1 so that the voltage between terminals TP11 and TP12 is DC 50mV to 250mV. Point A (Cathode of D29) V : 20V/div H : 2 msec/div DC range 1 : 1 probe 0V Point B (Anode of D30) V : 20V/div H : 2 msec/div DC range 1 : 1 probe 0V G Confirmation of Power Amp 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. Devices required Signal generator 8Ω or 6Ω load resistor Oscilloscope (dual trace type) Connection 1) Connect the output signal from the signal generator to the input terminal of YST-SW320. 2) Disconnect the connector terminal connected to the speaker unit and reconnect it to the load resistor. 3) Connect the HOT side of the oscilloscope CH1 probe to the point A or B indicated in the figure and the GND side to the GND of the main unit. 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. Setting 1) Set the signal generator to the sine wave, 100Hz and minimum output level settings. 2) Set the volume of YST-SW320 to the minimum position. 3) Turn on the power to YST-SW320. 4) Adjust the output level of the signal generator and the volume of YST-SW320 so that the output level observed at oscilloscope CH2 is 28Vp-p. Waveform observation With the settings made as described above, observe the waveform obtained at CH1 for judgment. Normal Normal Abnormal +B or GND level Becomes constant Abnormal -B or GND level Becomes constant G Confirmation of AUTO STANDBY Measuring Condition R60 = 1MΩ ➔1MΩ//10kΩ F = 100Hz Input Level = 4mV Load = Open Rating After 2 to 8 sec.
