Spring Line Hum

[Tony Allgood]

>I bet all those "low profile pcb mount" transformers made a shitload of
ACOUSTIC noise as well.

Absolutely. My DMP-8 Yamaha midi patch bay is a fantastic piece of
equipment but it hums very badly. I thought it was the mounting, but
nope, its the whole transformer. I may therefore have a go at using a
toroidal in its place.
