Circuitry not used in some versions. Circuitry used in some versions. Ground Chassis ground Common tie point Taken from common tie point

Schematic voltage source tie point.

Cabling: Heavy lines reduce use of multiple lines.

Waveforms and voltages are taken from ground, unless

noted otherwise.

Waveforms taken with triggered scope and keyed rainbow

generator. Waveform voltage is peak to peak. Timebase

is per division. Waveforms shown at 10 divisions. Supply voltages maintained as seen at input. Voltages measured with digital meter and a 1000µV RF

signal, with colorbar pattern, applied to antenna terminal. Controls adjusted for normal operation. Capacitors are 50 volts or less, 5% or greater unless noted. Electrolytic capacitors are 50 volts or less,

20% or greater unless noted. Resistors are 1/2W or less, 5% or greater unless noted. Value in ( ) used in some versions. Measurements with switching as shown, unless noted. Rated voltage shown on zener diodes.
