N O T E
U nless otherw ise specified, all of the voltage re ad ­
ings w ere taken w ith a dc vacuum -tube voltm eter
having an in p u t resistance of 11 m egohm s. T h e w ave­
form s show n w ere reproduced from actual ph o to ­
graphs. T h ere will be considerable v ariation betw een
in stru m en ts because of norm al m anufactu rin g to ler­
ances and vacuum -tube characteristics. T herefore,
the significance of any discrepancies observed should
be determ ined by re ferrin g to the circuit diagram .
All readings are in volts unless otherw ise specified.
W h ere tw o voltage readings are given, they represent
the voltage as read by a v o ltm e te r under tw o sets of
conditions, and, as such, do not indicate the peak-to-
peak excursion of voltage at the point.
