    Seems possible something has come loose inside, personally I'd take Alan up on his kind offer.

    Sorry to be long-winded but thought this might amuse some of you. Fortunately, I can laugh about it now.
    I am embarassed to admit that your description of events did make me chuckle.

    Could be the earth lead has come loose inside, worth having a look. Stick some internal photos up here if you like.

    I noticed when checking the connections yesterday that the hum is present whether the earth lead is connected to the phono preamp or not. So, I would like to take you up on your generous offer, if it still stands?

    Oh, what I have come across before (and quite possible what Alan has suggested in his PM) is, when removing the RCA cable itís easy to twist the plug and this can cause the socket to also twist. When this happens the positive and return wires can touch inside the unit where they are soldered to the RCA sockets. Iíve also seen something similar happen with the ground connection - all easy, quick and cheap fixes.

    Thanks for that. The preamp is going to have a trip to Alan for him to inspect. Would be no good for me to look as I wouldn't know what to look for!
