Hello

Search for "AC Power Source" on epay - many models from Elgar, California Instruments etc. Be prepared to pay a lot for shipping though - there is a lot of iron in them.

How much power ?
For up to a few hundred watts, an audio amplifier coupled to a transformer may be a good option.
angelG:
low power around 45W

Easy enough then, 400hz sinewave into a 100w audio amp, and a reversed mains transformer on the output
