Re-install the old tubes and see if the problem goes away. That might give a clue where the problem is. Also, look at the sockets and make sure they're not dirty. If there's a bad connection, sometimes it will act something like a detector and you'll hear the 50Kw AM boomer station nearby.
I had the same thing happen to me through my cousin. he was in rehearsal and we kept hearing a freaking radio station. We thought we were going crazy when it fact it was what we thought it was. SO my uncle checked it out and found that the sockets were dirty. Once he cleaned them, it went away.
Come to think of it, I think I've heard some kind of short wave radio over guitar amps before, too. Have you ever heard them pick up bits of broadcasts like a scanner?
