Stage gain measurements may be made with a vacuum tube
voltmeter to cheek circuit performance and to locate stages
which are not operating properly. The gain values listed may
have a tolerance of 20 per cent. Readings should be taken with
the AVC shorted to B minus.

The d-c voltage developed across t.he oscillator grid leak re-
sistor (Rl) averages 4.5 volts at 1000 kc.
Figure 4 shows typical tube pin voltages. All readings should
be made from the pins to B minus unless otherwise indicated.

The Alignment Procedure is given in table form. All i-f align-
ments may be made with the chassis removed from the cabinet.
However, the r-f alignments should be made with the chassis
and loop mounted in the cabinet, as the relative position of the
loop antenna with respect to the chassis materially affects the
The oscillator trimmer is accessible by tilting the chassis
slightly in the cabinet, The antenna trimmer is on the loop and
is accessible from the rear of the cabinet. The locations of these
trimmers are shown in Figure 3.
The output meter should be connected across the loudspeaker
voice coil terminals. The low side of the test oscillator should
be connected to B minus; the high side should be connected as
indicated in the Alignment Chart. During the entire alignment
procedure, the radio volume control should be in its maximum
position. The test oscillator output signal should be attenuated
so that the output meter reading never exceeds 1% volts.
