120Hz is ripple from the B+ supply. With 120Hz you will see two distinct bars floating up the screen.

60Hz will originate from the mains directly and you will see a single bar.

How many bars are there? Can you post a photo of the screen with the bars present?

And have you substituted the tuner tubes?
