NOTE: Make up a 6-8 turn, 6 inch diameter loop from insulated wire, connect to signal- generator leads, and place near radio loop.
For proper adjustment of the oscillator trimmer, fully open the tuning gang and insert a . 006 inch non-metallic shim between the heel of
the rotor and the top of the stator plates. Close the tuning gang sufficiently to hold the shim in place, and then remove the shins without
disturbing the gang setting.

ALIGNMENT PROCEDURE
General — Allow set and test equipment to warm up for fifteen
minutes before starting the alignment.
Dial Indicator — Before alignment, the chaI knob should be set as
follows: with the condenser gang plates fully meshed, the first
knob marking ( past the 550 KC point) should be in line with
the gold spot.
Output Indicator — Connect a 1000- ohms- per- volt a- c voltmeter or
an oscilloscope across the voice- coil terminals.
Signal Generator — Use an AM r- f signal generator. Connect the
ground lead to B—, and connect the output lead as indicated in
the alignment chart.
Output Level — Attenuate the signal- generator output throughout
the alignment so as to maintain the output below . 4 volts.
Radio Controls — Set the volume control to maximum. Set the
tuning control as indicated in the alignment chart. It is recom-
mended that a- c power be used when aligning the radio.
