SAFETY NOTES:
1.
DISCONNECTTHEACPLUG FROM THEAC OUTLET BEFORE
REP/AC/NC PARTS.
2.
SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS
POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS
OPERATING.
NOTES:
1.
The unit of resistance “ohm” is omitted (K = 1000 ohm, M
= 1 Meg ohm).
2.
All resistors are 1 I8 watt, unless otherwise noted.
3.
The unit of capacitance “F-is omitted (p =pF, p =&I.
4. The values in parentheses are the ones in the PB mode;
the values without parentheses are the ones in the REC
mode.
VOLTA’GE MEASUREMENTCONDITIONS:
1.
DC voltages are measured between points indicated and
chassis ground by VTVM, with AC220-240V, 50Hz
supplied to unit and all controls are set to normal viewing
picture unless otherwise noted. .
2. Voltages are measured with 1OOOOpV B & W or co/our
signal.
WAVEFORM MEASUREMENT CONDITIONS:
10000pV87.S percent modulated colour bar signal is fed into
tuner.
CAUTION:
This circuit diagram is original one.
Therefore there may be a
