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.
