Converting USA Domestic Electricity to UK Standard
By Kenneth Christ

In 240915 MMDigest, Paul Bellamy asked about running his 240-volt
50-cycle AC Bang & Olufsen CD player on 60-cycle power in North
America. He went on to claim: "A standard voltage transformer,
120 to 240 volts, will not drive the CD at the correct speed."
But I highly doubt this to be the case (I am a retired Electrical
Engineer) -- have you tried it?

A CD player does not use a synchronous motor like a turntable
does. Everything gets converted to DC to change the RPM of the CD
as it plays to maintain a constant tracking speed, and this is all
tightly regulated by a crystal clock and logic circuits, not the
line frequency.

I do feel confident that a simple step-up transformer will do the
job perfectly.
