[QUOTE="Family_Dog, post: 638146, member: 82"] I found the manual on Hifi manuals but only for the 'pure' 220/240v one, not the one with the US taps on the transformer. You need someone with a multimeter (ohms) range to sort out what is what. As a guide, there are probably two primary windings of around 110/120v each connected either in parallel for 120v or in series for 220/240 volts. The one leg should be the wire from the tapping that is physically closest to the core of the transformer. I agree with Charles, if you can sort it out, use the 240v tapping. Guess work is likely to result in blown components. Get someone competent to sort it out. -F_D [/QUOTE]
