4. When the receiver is not being used for a long period
of time, unplug the power cord from the a.c. outlet. HOT CHECK CIRCUIT
5. Potentials as high as 33kV are present when this
receiver is in operation. Operation of the receiver a.c. VOLTMETER
without the rear cover involves the danger of a shock
hazard from the receiver power supply. Servicing
should not be attempted by anyone who is not
familiar with the precautions necessary when working
on high voltage equipment. Always discharge the
anode of the tube.
6. After servicing make the following leakage current 2k 10 Watts WATER PIPE

1. Unplug the a.c. cord and connect a jumper between
the two prongs of the plug.

infinite.
LEAKAGE CURRENT HOT CHECK
1. Plug the a.c. cord directly into the a.c. outlet. Do not
use an isolation transformer for this check.
2. Connect a 2k 10W resistor in series with an
exposed metallic part on the receiver and an earth,
such as a water pipe.
3. Use an a.c. voltmeter with high impedance to
measure the potential across the resistor.
4. Check each exposed metallic part and check the
voltage at each point.
5. Reverse the a.c. plug at the outlet and repeat each of
the above measurements.
6. The potential at any point should not exceed
1.4V rms. In case a measurement is outside the limits
specified, there is a possibility of a shock hazard, and
the receiver should be repaired and rechecked before
it is returned to the customer.
