ALIGNMENT
INSTRUCTIONS
OF
TUNER
Alignment is an exacting procedure and should be undertaken only when necessary.
If alignment of AM and FM is required, either section may be done first.
The FM stereo section, however, should be done only if the FM monaural section is properly adjusted.
Notes:
Don't use a metallic screw
driver.
REQUIRED EQUIPMENT:
1.
Re

Pers
Signal generator with a frequency range of 455kHz to 1650kHz:
AM
Signal generator with a frequency range of 86.5MHz to 108.5MHz:
FM
Signal generator with a frequency output of 10.7MHz+0.5MHz:
FM
Vacuum tube voltmeter (AC-VTVM)
Sweep signal generator with a sweep range of at least 500kHz and center frequency of 10.7MHz with at least a 10.7MH:z
marker. (Ext. marker may be used.)
Oscilloscope with a wide range amplifier of approximately 100kHz.
Test loops, a coil of any size wire, one turn or more.
:
FM
stereo signal generator.
Audio signal generator with a frequency of 20Hz
to 100kHz.
Notes:
Allow the set at least five minutes
to warm
up before attempting alignment.
During alignment
keep the signd
generator output at the lowest level that will maintain a usable output from the set, except for FM stereo signal :
generator.
Take much care, lest the grounding of FM sweep signal generator input should make multipaths whic
made FM
IF alignment incorrect.
To avoid this the grounding lead may be connected through 0.01—0.04 MFD
capacitor to the tuner chassis when sweep generator is connected to the tuner section.
