EOUIPMENT
The MI·8319 identifies the equipment furnished with
the
power supply unit and consists of the following'
items:
1 - Vibrator Power Supply Unit, complete with vi·
brator and RCA·OZ4 rectifier tube.
I
- Power Cable, approximately 8 feet long. equipped
with power switch, fuse holder and fuse, terminals for
connecting
to the vibrator power supply unit, and ter·
minating in a plug for connecting to the associated
receiver.
DESCRIPTION
The MI-8319 vibrator power supply unit is pri'
marily designed for the purpose of adapting the Gen·
eral Purpose Communication Receiver (Model AR·88)
to 6-volt battery operation. Four rubber feet are pro·
vided for resting the unit on a table or shelf. If pre-
ferred, these feet may be removed to expose threaded
studs by which the unit may
be bolted permanently in
position.
NOTE - The power supply unit must be mounted with
the vibrator in an appToxima~ely vertical position.
Direct current at high potential is obtained by mean!!
of a non·synchronous vibrator used in conjunction
with a
step·up transformer. Rectification is obtained
by the use of an RCA·OZ4 rectifier tube. This power
unit has been designed and tested
to operate under a
wide variety of climatic conditions.
