MODEL 125 - P

ALIGNMENT: Should it become necessary at any time to check the alignment of this receiver, proceed as follows:

(1) Set the Signal Generator to 455 KC and connect to the Antenna Trimmer (Cl) of the Permeability Tuner. Connect the Signal Generator ground load to the chassis. Connect a suitable Output Meter acrom the Speaker Voice Coil Connections. Turn the Volume Control to the maximum position. Turn the Permeability Tuner to the extreme clockwise position (cores out of coils).

(2) Adjust the trimmers located at the top of the first and second I.F. Transformers for maximum output as indicated on the Output Meter.

(3) Set the Signal Generator to 1620 KC and loosely couple through a 2 or 3
tumn loop to the receiver loop.

(4) With the Permeability Tuner set at the extreme clockwise position (cores
out of coils), tune in the 1620 KC signal by means of the Oscillator
Trimmer (C2).

(5) Set the Signal Generator to 1500 KC and turn the Tuning Control so that
this frequency is indicated on the dial. Adjust the Antenna Trimmer (CI)
on the Permeability Tuner for maximum output.

(6) Set the Signal Generator to 600 KC and turn the Tuning Control so that this
frequency is indicated on the dial. Adjust the Oscillator Shunt Coil (C3) for maximum response while " rocking the Signal Generator. Rocheck the High Frequency Oscillator Trimmer (C2) and re-poak the Antenna Trimmer (CI) for maximum responde.
