I’ve been reading good reports on various fora of using a 240 to 12V AC transformer from Maplin as a relacement power supply for the Dacmagic. It’s a 36VA tranny in a plastic case with a captive 2 core mains cable and a selection of pluggable DC plugs. It’s Maplin part number L54BR. It costs £15.
I’ve picked up one locally so reports of some listening results very soon.
