@jkbtn, I see in one of your other posts that your Accuphase preamp is apparently a C-280. I took a look at its manual, which can be found at hifiengine.com if one is registered there, and it is described as having switches located behind a removeable part of the rear panel which allow the AC voltage it is operated with to be selected between 100, 117, 220, and 240 volts. I'm thinking that 20+ years ago it was probably set to 117 by you or whomever you purchased it from, if not by the manufacturer.
+1 to the good comments by Sleepwalker65. I suspect, btw, that Geoff's comment was a facetious reference to his use of "portable Panasonic CD players" that are battery powered :-)
Finally, I would re-emphasize my earlier reference to the possibility that running a component with 20% or so more AC voltage than it was intended to be used with may affect sonics. I find it ironic that some audiophiles concern themselves with minutiae such as which way a fuse is oriented, but it seems in many cases wouldn't think twice about the possibility that sonic consequences could result from such a major difference in voltage.
