Refer to Pictorial2-11 (Illustration Booklet, Page 7) for
the follow~ng steps.
SW5-R10-R11: Refer to
Detail2-11A and mount
the rotary switch with 5000 !1 (5k) and 10k
controls ( #63-1315) at its location on the circuit
board as follows:
1. Carefully align the pins of the front wafer (A)
with their holes in the circuit board .
2. Fit the pins of each switch wafer, one wafer at a
time,
into their board holes until all the switch
pins and the pins of control R11 are in place .
Then push the switch down tight against the
circuit board.
3. Carefully turn the circuit board over and solder
only the end pins in each wafer to the foil. In-
spect these switch pins to make sure all the pins
are tight against the printed side of the circuit
board. If they are not, reheat the connection and
push the switch tight against the board. Then
solder all the remaining switch and control pins
to the foil.
