Notes:-
I.
On early production the heater winding was grounded at centre instead of
at contact No. 2 on the W -6H6 socket. 2. The lower end of tone control R27 was to positive
plate supply terminal instead of to chassis frame. The wiring diagram is up-to-date.

R.F. Alignment Points
When adjusting the Air Dielectric R.F. trimmers, it is neces-
sary to use a special tool (See H-29644 in parts list) to slacken
the lock nut on the trimmer, previous to the adjustment, and to
tighten it
again after the adjustment. Another special tool
(See H-29643 in parts list) is available for making the actual
adjustment to the trimmer.
The adjustment should be made
upward or downward on the plunger with a twisting motion
The special tool designed by the Canadian Westinghouse Com-
pany for this purpose is double ended; one end having a pin for
the R.F. adjustments, the other end is a special socket screw
driver for use in making I.F. adjustments.
