    Ah, sorry mate, I have been negligent here! I completely forgot.

    If you want total silence, you must either use Toroidy.Pl or similar custom toroid manufacturer.

    Avoid Airlink. the last three I had from there have a mechanical hum which I hate with a vengeance.

    The one in your link is fine but as Alan said some shielding will be required. Loads available in China for £10 and they work really well.

    However there is a caveat. The tx isn't a toroid so the magnetic field is greater, unless you shield it very effectively or have a large case so it can be positioned far from the MC inputs you may have problems with induced hum.
    Also with the construction a lot of these examples have a low mechanical hum/buzz to them. If you want silence then look elsewhere.

    Thanks for the help Chaps! I'll look about a bit more and see what I can find

    I got a potted one from toroidy for about £60 more expensive than some but good quality and good service from them. You have to email them and they'll send you a quote etc as it's not part of their normal range.
    At the cutting edge of Numptyness!

    Is that a bit of a Christmas flounce over the “Boris Big Win” thread? Another reason why (IMO) discussion of politics (and religion) should be banned...

    Oh dear sorry to learn that . I hope all s well ...
    Alan, the phonostage is your design i believe.
    I m looking to upgrade from a Project job with 2 valves sticking out of it.
    My soldering skills are not bad. Feel this device would be something I could build.

    It is Sharin but I don't think there are any boards available.
