To clarify my previous post about FM alignment instructions on Sams and Philco manuals
The Philco instructions say connect signal to grid of 2nd IF tube and adjust FM detector secondary then primary (TC10,TC9) with tuning gang closed.
The Sams instructions say connect signal to grid of 1st IF tube and adjust 2nd IF secondary then primary then secondary of 1st IF (A10,A11,A12)
with tuning gang not closed.
That was only the first step for each method, there were more differences in subsequent steps.
AM alignment has tuning gang fully meshed in Philco instructions and tuning gang fully open in Sams insructions.
I hope this clarifies my previous post.
I will be following the Philco manual radio AM alignment.
