Another thing sometimes overlooked, if your set has the Standard Coil type tuner, is to adjust the local oscillator slug on the channel you're using for strongest picture and sound. You access the local oscillator slug for each channel in the tuner through a hole in the front of the chassis. Be cautious not to screw these in too far or the slug will disappear behind the threads, then you end up taking the tuner apart to get it back in place. Sometimes the slugs have already been tweaked by a previous owner beyond the threaded portion and appear to be missing. Usually the local oscillator adjustments are shown in Sams as part of alignment, but there is no harm in tweaking the local oscillator for any individual channel without doing the full video and sound IF alignment. What this does is to best center your RF source to whatever the current IF alignment is.
