Well I dissected the unit full out the transformer,supply its primary with 120VAC and found out that its secondary to be 22VAC center tapped (11-0-11)VAC unloaded. So what I did is to wind a transformer with 230 VAC input and 22VAC, center tapped output,using a magnet slightly bigger than the original design. Now connected to 2 12 Volts 150 Amp/Hour battery,it powers my computer,21" colored TV, the device is working perfectly.
What a great American design!
