I have a 51" plasma tv with 110V, i bought an avr for it with 110v socket, my avr is an omni 1000w. my tv only needs 102W, i plugged it in and its running smoothly, but i'm worried coz the input and output meter voltage of the avr reads 220V. should i be worried? or should i send the avr back and replace it? i was suppose to buy a step-down transformer but our electricity in my place is always flactuating so i decided to buy an avr instead. i appreciate any info i can get. tnx!
