    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?

    It's possible it could be the power supply unit, especially if it's a replacement type. Most cheapo replacements are only 300mA types that won't run hardly anything bar a Sega MS or Atari 2600. I'd check that out first (as well as the polarity!)
