I have a problem:

In many countries the AC power is 50 Hz instead of 60 Hz (like here in the
states).  This basically messes up american equipment taken overseas.  Clocks,
timers, electric induction motors, and such.  

I need a 500 - 1000 watt 60 Hz (110 VAC or 220 VAC) power supply and I can 
think of a couple of solutions:

1) Buy locally (overseas) -- generally expensive IF you can get equipment

2) Take a 60 Hz generator -- expensive (gas costs overseas), bulky, noisy 

3) Convert american equipment by replacing motor, timers, drive 
   ratios, etc -- what if the manufacturer didn't make a conversion kit, why
   change ALL the equipment if you could condition the power?

4) Run a 50 Hz motor into a 60 Hz generator -- bulky, inefficient 

5) A step up ocillator that runs on 50 Hz and produces 60 Hz.

      a) Transform 50 Hz power down to 12 VDC and use an inverter to produce
	 60 Hz 120 VAC -- not bad except it's going to be 50% efficient and 
	 I can't find anyone that makes it.

I would like to find a number 5 type solution if possible.  I don't mind 
making a #5, but I would prefer to buy one.

Oh, Radio Shack DOESN'T have it.

Please send suggestions, comments, manufacturer names & number, etc to the 
following E-mail address:
