SAFETY PRECAUTIONS (For u.s.a,)
Before servicing, unplug the power cord to prevent an electric shock.
When replacing parts, use only manufacturer’s recommended components for safety.
Check the condition of the power cord. Replace if wear or damage is evident.
After servicing, be sure to restore the lead dress, insulation barriers, insulation papers,
sheilds, etc.
Before returning the serviced equipment to the customer, be sure to make the following
insulation resistance test to prevent the customer from being exposed to a shock hazard.
INSULATION RESISTANCE TEST (For u.s.a.)
1.
2.
3.
Unplug the power cord and short the two prongs of the plug with a jumper wire.
Turn on the power switch.
Measure the resistance value with ohmmeter between the jumpered AC plug and each
exposed metal cabinet part, such as screwheads, antenna, control shafts, handle
brackets, etc. Equipment with antenna terminals should read between 3MQ and 5.2MQ to
all exposed parts’. (Fig. 1) Equipment without antenna terminals should read
approximately infinity to all exposed parts. (Fig. 2)
* Note: Some exposed parts may be isolated from the chassis by design. These will read
infinity.
. If the measurement is outside the specified limits, there is a possibility of a shock hazard.
The equipment should be repaired and rechecked before it is returned to the customer.

CAUTION (Refer to Fig. 9.)
Observe the following precautions when connecting a measuring device other than the accompanying speaker to an external speaker jack or a P.C.
Board.
Note:
When connecting an external measuring device to an output line, connect an electrolytic capacitor between them to cut the direct current. Also, the
positive (+) and negative (—) terminals of the left and right channels must be connected independently with respect to direct current and alternating
current. Be particularly careful that measuring devices connected to different channels and placed in close proximity to each other do not contact
each other.

Display Principle of the Spectrum Analyzer
The output signal (tape playback, line, or radio signal) from the tape amplifier circuit board passes through the power amplifier circuit and then is
input to Q400 and Q500 on the graphic equalizer circuit board. The output from Q400 and Q500 is divided into two signals. One is input to the graphic
equalizer circuit composed of Q401—Q405, Q501—505, VR400—409, and VR400—404, and after its 100 Hz, 330 Hz, 1 kHz, 3.3 kHz, and 12.5 kHz
frequency components have been attenuated or amplified between —10 dB and +10 dB by the respective graphic equalizer controls, the signal is
fed back to Q400 and Q500 and added ito the original sound.
The other signal passes through the balance and volume controls and, in addition to being input to the power amplifier, it is sent through R404 and
R504 to the Q600 and Q617 amplifiers as a left and right mixed signal. The output of these amplifiers is input to the |C200—-1C203 band pass filter
and then is passed through a smoothing circuit composed of a diode and a condenser from which it is output as a DC signal. The selective
frequencies of the band pass filter are determined by the value of the CR attached to the outside of each IC.
IC Selective Frequencies
Output pin No. 1C200-8 1C200-2 1C201-8 1C201-2 IC202-8 1C202-2 1C203-8 1C203-2
Further, in 1C205 208 Hz signals each with shifted phases are made and output from pins 9-16. These are then sent to the |C207 grid driver and
Q601—608 sampling gates. The signal sent to C207 is inverted and then input to grids 1—8 of the F/L meter. The signal converted to a DC signal by
IC200-IC 203 and their peripheral circuits is input to sampling gates Q601—Q608, and when a low signal is then input to the base of each gate, the
gate closes and the signal is output to pin 4 of IC204.
The DC signal input to 1C204 is converted to a seven-step meter drive signal and input to 1C206, from which it is output to the F/L meter as a segment
drive signal.
In addition to the above grid drive signal and segment drive signal, a 322 Hz AC voltage is applied to the F/L meter by a DC/AC converter circuit
composed of Q612, Q613 and T600 and used as the power supply for the filament.
