Note :

• All capacitors are in µF unless otherwise noted.

• pF : µµF 50WV or less are not indicated except for

electrolytic types.

• Indication of resistance, which does not have one for

rating electrical power, is as follows.

Pitch : 5mm

Electrical power rating : 1/4W

• Chip resistors are 1/10W

• All resistors are in ohms.

k = 1000 ohms, M = 1000,000 ohms

• : nonflammable resistor.

• : fusible resistor.

• : internal component.

• : panel designation or adjustment for repair.

• All variable and adjustable resistors have

characteristic curve B, unless otherwise noted.

• All voltages are in Volts.

• Readings are taken with a 10Mohm digital mutimeter.

• Readings are taken with a color bar input signal.

• Voltage variations may be noted due to normal production

tolerences.

•:B+bus.

• : B - bus.

• : RF signal path.

• : earth - ground.

• : earth - chassis.
