"Special Tuning Note:
If two different capacitance settings for C4E (Osc) can be
found at which the ouput is at maximum, be sure to use only
the setting corresponding to the higher capacitance.
The maximum capacitance position of the rotors of all air
trimming
capacitors (except the auxiliary trimmers C4F and C4G under
the gang capacitor shield) is obtained when the top of the
"cross"
or "arrow" on the rotor shaft is lined-up with the fixed fiducial
mark
on the dust shield, IF can or chassis. Turning the rotor 180
degrees
in either direction reduces the capacitance to a minimum.
When trimming a circuit always tune in a counter-clockwise motion
from the maximum setting. This will always result in a setting
such
that a clockwise motion increases capacitance...."
