9-2. SCHEMATIC DIAGRAMS

Note:
• All capacitors are in µF unless otherwise noted. pF: µµF 50WV or
less are not indicated except for electrolytics.
• Indication of resistance, which does not have one for rating elec-
trical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4W
• All resistors are in ohms. (1MΩ: 1000kΩ, 1kΩ: 1000Ω)
• Chip resister are 1/10W unless otherwise noted.
• : panel designation and adjustment repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• METAL FILM (:RN, :RN-CP) resister in 1%, 0.5%, 1/4W unless
otherwise specified.
• All voltages are in V.
• Reading are taken with Hivision color-bar signal (R.G.B) input.
• Voltage are dc with respect to ground unless otherwise noted.
• Reading are taken with attach the BVM series monitor.
• Voltage variation may be noted due to normal production tolerancd.
• : B+, B– line
• : signal path
• Circled numbers are waveforms reference.
