My shielding attempts made no difference. I also unbolted the transformer
so I could move it around slightly (as much as the leads would allow). That
had no effect.
I think my next step will be to remove the transformer + power board from
the chassis and run it on the bench. That should stop the noise if its
magnetic. Might replace the bridge rectifier while I have the power board
out.... its a $2 part (VJ048 - NTE53000 equivalent).
