NOTE
Unless otherwise specified, all of the voltage read
ings were taken with a dc vacuum-tube voltmeter
having an input resistance of 11 megohms. The wave
forms shown were reproduced from actual photo
graphs. There w ill be considerable variation between
instruments because of normal manufacturing toler
ances and vacuum-tube characteristics. Therefore,
the significance of any discrepancies observed should
be determined by referring to the circuit diagram.
A ll readings are in volts unless otherwise specified.
Where two voltage readings are given, they represent
the voltage as read by a voltmeter under two sets of
conditions, and, as such, do not indicate the peak-to-
peak excursion of voltage at the point.
