Hi Jim, you may have a problem similar to mine. In Sydney, with a nominal supply voltage of 240 Volts, the supply at my place is above 250 volts. The supply authority says that is in the limits of their specification. I do not know why they run it so high, maybe they think they will sell more power. The problem is that many appliances have a 240 or 250 maximum, dual power supplies for 110 V switch to take 220 V. My solution is to run my lab through a step down transformer to about 210 volts. It puts less pressure on the capacitors in the power supplies. I have not had a power supply problem for about 4 years now. cheers, Neville Michie
