6-3. SCHEMATIC DIAGRAMS

Note:
• Capacitors without voltage indication are all 50V.
• All resistors are in ohms.
kΩ=1000Ω, MΩ=1000kΩ
• Indication of resistance, which dose not have one for rating electrical power, is
as follows.
Pitch : 5mm
Rating electrical power : 1 / W
4
• : nonflammable resistor.
• : fusible resistor.
• : internal component.
• : panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless other-
wise noted.
• : earth-chassis.
• Readings are taken with a PAL color-bar signal input.
• Readings are taken with a 10MΩ digital multimeter.
• Voltages are dc with respect to ground unless otherwise noted.
• Voltage variations may be noted due to normal production tolerances.
• All voltages are in V.
* : Measurement impossibillity.
• Circled numbers are waveform references.

Note: The symbol display is on the component slde.
The components identified by shading and mark
C
are critical for safety. Replace only with part number
specified.
The symbol indicate fast operating fuse.
Replace only with fuse of same rating as maked.
A
• : B+ bus.
• : B– bus.
• : signal path.(RF)
