Hi Ingo!

Unshielded twisted pair.

Yup.

I'm sure you can, but you may find it too loud.  I can't remember if there
were wattage ratings on the transformers or not.

>Where did you get the tranformers?  Is the "70.7V LINE MATCHING
>TRANSFORMER" listed at http://www.parts-express.com the right thing to
>use?
Radio Shack, but I don't think they still carry them.  The ones at
parts-express look right, but it's hard to tell with just a picture.

> I know, lots of questions...  sorry.
No problem!

Cheers!
