Hi Jeff - I've just tried to take a photo, but my camera has decided not to play along (it is a while since I used it, so I think it feels neglected). I've also trawled the net to find a picture, but can't find a hide nor a hair of one.

I'm sure I saw a picture of one on ths board somewhere (I've only just joined, and spent a rainy day reading as much as I could - so much, that I can't remember what I read where!)

Will keep trying with the camera, but yes, from what I am told it connects to three pots and a transformer (although in my house it will connecte to three PBX extensions instead)

John
