- The easy trick is to borrow an IDOS ($150) from your hifi shop and see
- if the hum goes away. Also easy to do it get a power strip with emi and
- surge protection for $15 and isolate a pair of outlets with a teflon
- washer. Make sure you don't fool around with the insides unless you
- use a proper ground!
