So I still need to find a US power supply that offers the higher voltage DC out (higher than the 16K / 48K) that the Spectrum 128 requires. Anyone have any ideas of a compatible unit?
Tnx.

But if I could find a native, American PSU that output the proper DC voltage, then there would be no overheating. (As opposed to putting the Euro PSU on a power converter that changed voltage but not Hz.) Am I mistaken here?
