VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on
exclusive AC adaptor and the stable supply voltage
of AC 120V.  Signals are fed by a colour bar signal
generator for servicing purpose and the above
voltages are measured with a 20k ohm/V tester.
INDICATION OF RESISTOR & CAPACI-
TOR:
RESISTOR
1. The unit of resistance “
Ω
” is omitted.
(K=k
Ω
=1000 
Ω
,  M=M
Ω
).
2. All resistors are ± 5%,  unless otherwise noted.
(J= ± 5%, F= ± 1%, D= ± 0.5%)
3. All resistors are 1/16W,  unless otherwise noted.
4. All resistors are Carbon type,  unless otherwise
noted.
