[Hallicrafters] Aligning a S-76

[Richard Knoppow]

        The procedure in the book uses the detector diode load as the 
point of measurement.   Since the AVC line is being used a very high 
impedance VTVM is desirable.  The generator injection point is the grid 
of the first  50khz IF.   No DC there so decoupling the generator is not 
necessary.  Presumably the amplifier isolates the first  50Khz  filter 
from being loaded by the generator.  This should work.   I think there 
is a Sams folder on BAMA along with the Hallicrafters book but I believe 
it has the same procedure in it.
