The input coils are factory adjusted and do not require any
further alignment.
The brass spring and the metal spacer form a safety
"interlock" which grounds the high voltage power supply
and removes the high voltage from points which are exposed
when the perforated cover
is
removed.
Refer to the chassis photographs for the location of the
interlock and the resistance test points.

IMPORTANT: Refer to Figure 1, push down the brass
spring of the interlock, and temporarily insert a rubber
foot between the brass spring and the metal spacer. If
you fail to do this, the high voltage circuit will be
short-circuited, you will be unable to obtain a plate
connector resistance reading, and damage will result if
power is applied.

The resistance between the plate connectors and the
chassis should measure approximately 200 k51 after
the meter stabilizes.
The resistance between lug 3 of each tube socket and
the
chassis
(Pictorial
4-14)
should
measure
approximately 20 5 1 .
