I shudder to think how this effect was discovered...
talk about
heisenbugs! Imagine some poor microwave receiver person trying
to find a loss of sensitivity, birdies, spurious output... and
finding out it's some goddamn FRONT PANEL LIGHT BULB!
I would suspect a bigger bulb would be needed. High current is needed to
make the magnetic field.
Do you have any references to this? I have a friend
who would
appreciate such horrors...
It was discussed amongst the tube geeks a couple of years ago, I think at
the big Rochester radio show.
