Hi Guys,
Well, summer is over so it's time to get back to the winter hobby.
I'm working on a Zenith R723 AM/FM. All caps have been replaced resistors check and Th IF alignment is done. My problem is that when doing the RF alignment, when one part of the dial lines up with the right freq., the rest of the dial is off. If I set adjust it so 103MHz is correct on the dial. then 95 comes in at 92 on the dial. All freq above 103 line up but anything below is off.
Any ideas?
Thanks,
