Hummm....your output on the 5 volt winding depends on what your input 
voltage...my guess is that your not running full input voltage!

If your running exactly 120VAC and still not getting 5 VAC..then I think 
your experiencing a problem with the MOT primary! Sounds like you have an 
OLD MOT from the sounds of things!! I've had a couple of these before.
MOT's buzz depends on core size** Small MOT's buzz loudly...while bigger 
ones output little sound at all, making them REALLY DANGEROUS...you can 
never tell if they are energized or not.
