I have a relatively old surround sound receiver/amplifier.
The power supply generates a lot of broad band RFI but I hear it mainly on VHF.
This happens even when the amp is in standby.
Unplug the amp from the mains and all noise goes away.
I could look at replacing the amp but would first like to take a look at seeing if I can sort out the issue.
Where would be a good place on the PS to start placing ferrite beads etc.
Thanks.
