Install switch "C" (P14-285) at location SC. Use a 3/8
' I
control hex nut, 3/8" control
lockwasher, and a "Bakelite" panel washer. See Figure 9. Before tightening panel
nut, be sure switch is in extreme counterclockwise position. Orient switch so flat
side of shaft is directly opposite the "1 " marking on the panel. Check by placing one
of the large pointer knobs on the shaft and tightening the set screw. Make sure the
set screw is tightened against the flat side of the shaft. Reposition switch
if
pointer
does not line up with the "1" marking. Retighten pointer knob on shaft. Check to
make sure sufficient clearance has been allowed between switch resistors and side
of chassis.

FINAL WIRING
REFER TO FIGURES 12 AND 13.
NOTE: All power transformer leads have been trimmed to proper length and tinned for easy
connection into the circuit.
