Doctor, it hurts when I do this...

OK, I'm a smart-ass. As soon as I read the original post I had this image
of Groucho Marx dressed in a Dr's smock & head reflector replying, "Well,
don't do that!".

Pulled the amp from an old phono player. It was intended to be mounted
with the tubes horizontally. I want to situate it vertically. When I
do so I get a lot of hum. If I turn it upright, the way they intended,
it's much quieter. Can someone explain why this might be? Can I unbolt
the power transformer and rotate it 90 degrees? Thanks to all.
