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.
