Which looks even better suited to what you want (and cheaper too).
Just cos they say PCB mounted doesn't stop you soldering wires directly on the
pins does it? :)

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.

-ken I've been looking around for a 1:1 line level
transformer to lift the ground when connecting the headphone stereo output jack of a
laptop or iPod to a consumer-grade amp that takes a headphone jack input.
All I've been able to find is insanely expensive, like US$200.

That's ridiculous. I just need the transformer itself; I can connectorize it myself.
But my searches (Jameco, Mouser, DigiKey) aren't turning up anything except POWER
transformers, much larger than what I need.
Can anyone point me to some part numbers and (reasonable) prices for a 1:1 line level
transformer?
Thanks.

I don't think that's insanely expensive :) given that jensen are
probably one of the best at this sort of thing and their transformers
are used in many professional grade applications - and if you are going
to transformer-couple things then the quality of the transformer is
absolutely critical (even to get consumer grade performance) and
requires specialist knowledge and manufacture to get right (or a lot of
luck!). There may be other options that don't require a transformer -
it depends upon the problem you are trying to solve.
