Hi
As some of you may know there are sometimes a risk to get a lot of mechanical hum from toroid transformers due to a DC component on the mains voltage.
I have read somwhere that Jeff Rowland in his amplifiers use a circuit consisting of diodes and capacitors between mains and transformer in order to remove the DC component.
Has anyone any information on how this circuit look like? I can imagine that you can build it using 2 Zener diode connected in series but I wonder if anyone have any idea how it is done in Jeff Rowland amplifiers?
