    Default CM12U replacement transformer

    The secondary winding of my CM12U has gone open circuit probably due to the well known issues with overheating.

    I can't seem to find a like for like replacement so was going to purchase a 240 volt with 0-18 0-18 secondaries but have a couple of questions that I hoped people here could answer

    Am I correct in assuming I can do without the centre tap on the primary and what does anyone know what VA rating I should opt for on the secondary ?

    I am not bothered about the existing casing so if anyone has successfully replaced the transformer I would be greatful for any advice.

    Thanks

    Have a look here www.geocities.com/ido_bartana/ he has quite a good X10 site with plenty of info on mods. The site might have the info you need or point you in the right direction.
    Good luck

    @toscal,

    Thanks for the reply, unfortunately I have searched the web and checked out the above site without success.

    I have ordered a couple of transformers and will let everyone know how I get on.

    Cheers
