It must be 10 years now since I first read this article on how to wire the mains :http://www.soundstage.com/weaver01.htm
Recently I came up to an update on this, saved it somewhere then lost the link.
Typical for my receding memory, and hairline
Anyhow, I thought its was just about time I tried out the tweak, only with a twist: first try by listening tests, then measure the voltages and confirm the actual tweak.
Well, I tried the first polarity change, taking notes all along, and then prety much gave up: cannot seem to find any time to listen to music, much less go on experimenting
But, I haven't lost hope yet, my summer vacation is coming up fast! That's 2 weeks of happy tweaking for me
Yes, Charlie - I read the same article about 10 years ago, too!
Although the one I have (I printed it out) is slightly different - much longer!

I do this test as a matter of course with all the kit I build - in fact, I always use a DPDT mains switch which has the active & neutral reversed on one side, for easy switching/comparing. However, IMO the way you should really
go about it is (forget the 'listening'!):
* make up a short (1' long) extension cord which swaps the mains polarity
* plug the device into the wall normally and measure the voltage, as the article describes
* then plug it into the 'reversed' extension cord and re-measure
* if the latter config is the lower voltage, you need to reverse the pair of wires to the mains transformer, at the mains switch. That way, the fuse remains on the 'active' line.
