Hum from Atma-Sphere MP-1 Power Supply?

Maybe Ralph can answer this: My MP-1 PS makes a loud hum, which is temporarily stopped for a few minyes after changing the fuse - even just taking it out and re-seating it. Then it comes back. No new TT or appliance in system. Any thoughts?

Sounds like the transformer is on the way out. It happened to MP-1 and it got progressively worse until the unit shut down. Time for a visit to Lake Woebegone.
