The power supply that came with my (US supplied) Empeg is definitely *not* suitable for use with 240VAC ! However, any UK power supply with the correct polarity & 12-16VDC output should be fine. The one from my scanner works OK, as does one I found at work that was originally used with an external CDRW drive.
