The more common thing in older sets was sound buzz due to IF/sound misalignment - tends to occur when bright sharp details are present, like white letters.

Would a sound misalignment contribute to the buzzing being intermittent and being present whether there is a video source connected or not?
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?
