deliver potential that only varies
slightly, due to the cOmmutator ripple.
In sections where direct current is
used for house lighting, a motor gen
orator set Is the only practical and
satisfactory source of plate potential.
Taking first cost, maintenance cost,
convenience and space required into
consideration. the best way to obtain
the required current potential for the
operation Of vacuum tube transmit
tiers, Is by the use Of a step-up trans
former and rectifying tubes.
A line of vacuum tube rectifiers is
on the market under the name ken
otrOns." These tubes have been de-
signed TO have the proper operating
characteristics to rectify alternating
current for the line of transmitting
tubes put on the market by the same
company.
If radiotron transmitting tubes are
used it is only necessary to build or
purchase a transformer with a fla
ment heating winding and a plate cur
rent winding and by the use of keno
irons for rectifiers. The entire power
to operate the transmitting set can be
taken from the alternating current
house lighting circuit
1t is possible to use an electrolytic
rectifier in order to rectify the plate
potential after the 10 volt house
lighting circuit has been stepped up
by means of transformer. Electro
lytic rectifiers are probably the cheap
est source of plate potential, but they
are sloppy and demand lot of care
and attention.
To operate the standard five-watt
transmitting tube, known as radio
iron type wv POP. plate voltage
OF $50 is required and the plate cur
rent per tube Is 45-10O of an ampere.
The filament requires 2.35 amperes at
rs volts. Rectifying tubes known as
kentron type wv PIG are made to
be used In conjunction with the five
watt transmitting tubes The rectl-
fer tubes are so designed that one rec
tlfier will rectify sufficient current mt
the correct potential to operate one
transmitting tube.
Figure "A" shows how single
transformer can be used to furnish
all of the necessary plate and fila
ment current for tube tra1smitter.
For those who do not wish TO be
bothered with the trouble and expense
of rectifiers, there is a circuit known
as the self-rectlfying circuit that can
be used for radio telegraphy. In
using self-rectlfyng circuit at least
two tubes must be employed. II more
power is desired tubes must be added
in pairs The tubes employed are di-
vided into two groups operating on
each half of the cycle.

RADIO
THREE SOURCES OF
PLATE POTENTIAL
Use Of Step-Up Transformer and
Reetifying Tubes Recon-
mended for Amateurs.

The greatest drawback in the use
Of vacuum tubes for radio transmit
ters is suitable source of direct cur
rent potential for the plate circuits
In general there are three sources,
batteries, motor-generator set, and
rectified alternating current. The al
ternating house lighting current can
be stepped up to the required poten-
tial by means of transformer and
then rectified by an electrolytic rec
tifier, by the use of vacuum tubes
manufactured for this purpose.
The use of batteries as source of
plate current potential is limited to
very low power sets that are used
infrequently, and then only for short
intervals. Sufficient capacity in the
form of "B" batteries would mean
HOt only relatively high first cost
but also an extremely high mainte-
nance cost. A mOtor-generatOr set,
while high in first cost, will leave an
extremely low maintenance cost and
