DESCRIPTION
The MASTR ® II Multiple Receiver Power Supply is
designed for supplying a maximum of eight MASTR II
auxiliary receivers. The supply will operate at 60 Hertz
(Model 19E501707G4) or 50 Hertz (Model 19E501707G5).
An audio power amplifier is included in the supply along with
a speaker mounted on the front panel. A switch is provided
for connecting each receiver line audio output to the amplifier
and speaker. The receiver audio PA is not used in multiple
auxiliary receiver applications.
Modification Kit 19A137630G1 (Option 9707) provides
a metering circuit and meter mounted to the front panel of the
supply. This kit allows functional checks of up to eight
receivers. The metering points are the same as in the MASTR
II station receivers.

FOR
MAINTENANCE
To insure high operating efficiency and to prevent me-
chanical and electrical failures from interrupting system op-
erations, routine checks should be made of all mechanical and
electrical parts at regular intervals. To check the Auxiliary
Receiver functions, refer to the Test Procedure (see Table of
Contents).
CIRCUIT ANALYSIS
Multiple Receiver Station Power SupplyWhen the power
supply ON-OFF switch S801 is in the ON position, 121 VAC
is connected across the primary of T801 (T802 in the 50 Hz
model). The power transformer is a ferro-resonant type which
has inherent good line regulation. C801 serves as a resonating
capacitor across the secondary taps of the transformer.
