Step down transformers detrimental to SQ?

Incidentally, and this is probably nothing, but I am curious to know if this is an older vintage type amp? And where was it made?

Again, there's no problem with higher voltage. Its lower that tends to cause problems. And since if you go back to say early 1900's America (or 'modern' day California) you were much more likely to encounter low voltage situations, its possible they were designing (and labeling) electronics for those somewhat lower voltages.

Either that, or it was made somewhere with substandard (by modern standards) electricity (like, you know, California) or maybe even somewhere foreign. Like.... all together now.... California.

Kidding. California would get the label right.

But seriously: vintage? Country?

@bsmg I was under impression that I need a step down because the voltage from my wall is higher than the amp spec.

Sorry; you’re correct. I misunderstood what you were asking.

Don’t know where millercarbon is but my power conditioner shows a digital voltage readout when it’s on and I’ve never seen it drop below 121V and most of the time it reads 123V,,,,,,in northeast TN hard by the VA border.

And you're lucky with that 220V stuff......I once plugged in a 110V blow dryer in Manila; it ran real fast for about 2 seconds and died.

@millercarbon No one makes them? Huh ... here are two good ones

Sounds like you bought a Luxman on Ebay. :)

Best,

Yeah, just get acupwr and you should be fine. I heard good things about them, I would not save a few dollars on this device.
As for sound quality..shouldn't make things better, I'd say. You will want a very good low gauge power cord for amp, anyway.
