Notes:
1.
The constants of some resistors are changed as follows.
R818 — 330 k2, R819 — 1.6 kQ, R820 — 2 kQ, R821 — 120 kQ
2.
The varistor diode D807 is connected to R819 in series as an addition.
3.
The position to insert C826 10 u/50 V N.P.C. is changed from the area between
@)- @ to the area between @)- @) .
4.
Voltage values in [___] are measured with a tester (impedance 20 kQ/V) without
a signal applied to the unit.
5.
indicates positive B power supply.
6.
indicates the signal path.
Ts
When replacing the parts in the darkened area( _
), be sure to use the designated
