Hi Guys,
I finally completed the cabinet on my 48-482 and thought I'd go back and give it one last alignment following the FM alignment procedure to the letter.
There is one point that I don't understand.
It says: It is essential that the output from the generator be kept below the point where the detector-oscillator locks in, otherwise an erroneous zero-beat will be obtained. When a single very sharp zero-beat point is obtained, the adjustment is correct.
Can anyone explain this to me?
Thanks.
