   Also most likely 50 htz.

  Two syllables: Variac. Little one, 2 amps is more than enough. It is
quite possible that you'll slowly fry the power transformer - it will
always run hot on USA mains. If you can score a cheap small variac, you
can run it on 90 or 95 volts and it undoubtedly will be happy.

  If it has an external 'brick', then you can substitute that for
something that puts out the voltages the Tomy needs.

  But I'd be *real* leery of running lagacy Japanese linear power supplies
on 117/60 lines.

  Domo arrigato.
