That's a good question, with no simple answer. The recognised methods are: 1) use an RF/EMI sniffer - I have one that was made by Russ Andrews years ago but I don't know if they still sell them. It works somewhat like those DIY tools for locating pipes and wires in walls... It is very sensitive. 2) use an old AM radio tuned between stations (not as good as option 1) - this method can detect supplies that are spewing out rf 3) Use a battery-powered oscilloscope to look directly at the mains - this option is for experts ONLY, is dangerous and requires specialised equipment: see here: http://www.marcspages.co.uk/pq/4120.htm 4) Ears! - replace suspected device with a known clean supply (I have a Lab supply with adjustable voltage and current for this purpose) and see if the sound of your system changes. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
