I don't have any equipment to do an IF/sound alignment. Is this something where I could adjust the sound/IF transformer and do it by ear to see if the buzzing goes away when I make an adjustment?

1) If this is not an old tube set, my comment doesn't apply.
2) Do not touch any alignment adjustments without the right equipment. You will only make it worse. The only things that are safe to try are an AGC control or a sound buzz control if the set has one (typically on old tube Zeniths, I think).
When you say video source are you referring to a RF antenna source or RCA composite input? A buzz affected by IF alignment would come and go according to different image content on an antenna signal. If it is doing it on composite input or doing it randomly independent of the video content, then it's something besides alignment, quite possibly grounding or shielding between circuits.
