One last mod for awhile. I converted a broken old rack-mount Surge Protector into an External Power Supply for my Bozak ISO-X. With my other recent equipment upgrades, its noise floor became more and more apparent. This vastly improves the clarity of the unit besides.
On the back, I reused one of the existing power plugs as the connector. I'm sure reusing an AC cable as a power interconnect breaks a dozen UL regulations, but I'm going to get a short IEC Kettle Cable and cover it in red electrical tape.
