(a) Connect the ground lead of the test oscillator to the chassis frame. Connect a .5 mld. condenser
in series with the other lead and oonnect this lead ro the grid cap ofthe 6K/ tube, leaving the
tube's grid dip in place. The .5 mid. Condenser is necessary to pwvent the Osrillator Circuit

(i) ln order to insure accurate settings oi the 1. F. trimmers the shove adjustments should he
repeated using the lowest oscillator output that will give a reasonable output meter scale

(a) Connect the output of the test oscillator to the antenna connection of the rcceiver and to the
cltasis ground. D0 not use the 45 mid. condenser that was required in aligning the l. F. stages.

(b) Tum the rotor plates of the _gang condenser until they are COMPLETELY OUT OF MESH.

(d) Adjust the oscillator section (middle section) ol the gang condenser cAREFuLLY tor mam.

(i) Tum the oondenser rotor plata until the 1400 K. C. signal from the test oscillator is tuned
in with maximum output. (No calibration blocks should be used as the Oscillator circuit is
