Hi Alec and Bill,
Appreciated your collective comments regarding the power supply. I dare say the transformer in the KN series does have multiple taps because it would not be cost effective (I wouldn't think, anyway) to manufacture a transformer limited to a single voltage input. To do so would require a range of transformers to meet all voltages around the world. There is too much thought, engineering, and sophistication in the KNs to believe Panasonic would go that route.
I wish I had a schematic of the power supply. It would tell us if there are multiple taps. With that information I might be tempted to take the back off and change taps. Used to disassemble radar and laser systems down to the last diode and rebuild them using schematics years ago.
Bill, your suggestion to have a universal power supply like those in laptops would be the ideal solution. It would be interesting to know Panasonic's rationale for their power supply design. Perhaps it is as you suggest, Alec, to deter the grey market. On the other hand, grey market products have a power supply anyway, so perhaps Panasonic's design is for other reasons? Let's hope the KN7000 is multi-voltage. If it is I would likely buy one. If it isn't, there is no way I would buy one because my KN6000/6500 does it all already - for me at least.
Thanks again, guys, for your comments.
Chuck

Hi Alec, First I realise that this is a bit off topic but still relevant.(Apologies) As you probably know, I design electronic instruments for a living and all our devices include a built-in universal switched mode supply, or, if portable and battery driven, a switched mode DC-DC converter. Ok, we do use quite a bit of filtering, but these instruments work with sensors which produce sometimes just a few microvolts of signal and we still manage to produce perfectly good noise free results. We are only a small firm but we export all over the world, as Matsush*ta do, and have to cope with the varying available supply voltages (sometimes as low as 95Volts AC in Japan!). I don't think it would be too much trouble for them to incorporate a suitable universal power supply, considering the resources at their disposal.

The following suggests to me that it is a Technote site on behalf of Technics UK. I guess it could be similar to the kn6000 site which Technote ran when the KN6000 was launched.
