    My Guyatone amp has a switch on the back labeled 100V and 117V I live in the united states. Im not sure I understand the purpose of this switch. Is it to match your wall voltage?

    Yes it is to match your wall voltage. Japan used to be on 100v.

    is it strange to have the voltage on the switch lower than in my house? i think my house is around 121v.

    i was thinking well maybe 117 is closer to voltage in the 70s. But I was looking at my new Genz Benz Neo Pak 3.5 and the voltage switch on it is 115v or 225v.

    I believe Japan is still on 100V 50 or 60 hertz depending on the region.

    Voltages have been creeping upward over the last couple decades and for much of the US 120 is nominal with variations of 5V up and down. Where I live we're pretty much at 122 most of the time.

    thats what I mean. Why would a brand new amp (the neo-pak) have its voltage set at 115v?

    sorry that is what I was trying to say in the earlier post. why not 120v?

    Uh, slow catching up?

    A few percent one way or the other doesn't mean much in a world of tubes where tolerances are way wider than that.
