A : B+ Line.
•
B : B– Line.
•
C : adjustment for repair.
• Power voltage is dc 14.4V and fed with regulated dc pow-
er supply from +12V and REM terminals.
• Voltage and waveform are dc with respect to ground un-
der no-signal condition.
• Voltages are taken with a VOM (Input impedance 10
M
Ω).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.

X : Parts extracted from the component side.
•
: Pattern from the side which enables seeing.
Note: The components identifi ed by mark
0 or dotted
line with mark
0 are critical for safety.
Replace only with part number specifi ed.
