AGC ZERO SIGNAL BIAS
With the power turned OFF, connect the VOM to test
point three (TP3) as shown in Figure 20.
Check that the VOM is adjusted to read 9 volts DC and
turn the power ON. The voltmeter should read

T3 TEST
With the power turned OFF, connect the positive lead of
the VOM to TP5 and the negative lead to TP10. Make
sure that the VOM is set to read 9 volts DC and turn the
power ON. The voltage on the VOM should be the same
If you do not have an RF generator, go to Section 3.

than 0.5 volts from this value, turn the power OFF and
check the polarity of D1, and resistors R11 and R5. Also
check that transformer T1 is properly installed.

turn OFF the power and check that T3 is properly
installed.
