    Indeed, though the pic in the link shows the lead into the plug with an earth, which would imply a non double-insulated bit of kit! Someone should report this, it could kill somebody.

    Hi,

    It's been selling for decades - so someone must be buying it. There's a Swiss connection, I think. Don't know if they make it or buy it because of their concerns with radiated fields. It simply gives an indication of A.C. leakage to earth; a (cheap) voltmeter would tell you more. Switch to A.C. range connect one probe to the plug's earth and the other to the chass and note the reading. Ideally, reverse the transformer's primary connections and measure again. One connection should give a lower reading and you do this with all components, which is said to lead to an improvement in sound quality. Haven' been able to read the P.D.F. so apologies if I'm just repeating what it says.

    Kind Regards,
    Stephent

    A friend of mine has one that he picked up in a charity shop - neither of us have ever tried to use it though.

    No matter how little one has on, there always seems to be something better to do

    Have none of you ever tried plugging a Telefunken mains lead into a portable player, playing a piece of music, and then switching over at the Telefunken plug end and playing the same thing again?

    There are quite audible differences.

    There should't be, after all as I said earlier transformers really don't care which way they are fed as long as there is no Earth connection involved.

    Live & Neutral are thus one & the same with the plug you mentioned.

    You did say 'portable player' though...

    So I guess that means you can't quantify the mains being fed to it. After all, all you are listening to is a power supply & that is the mains

    It changes 50 times a second in the UK, so even a few seconds out it may well sound different

    I'm off to bed

    All the bests Chris
