1:1 Isolation transformer needed

[nirvanas silence]

I need one with primary and secondary resistances around 500 ohms, and I really can't find one with leads rather than PCB mount.  Anyone know where I can get a few besides radio shack (ick!).

hmm ratshack is 600 ohms is taht two much?

[nirvanas silence]

Even if it works, $4 each is a bit too much and their products are junk.

[Ansil]

hmmm well i understand but i have used the one in question for years.. and no problems..  

uh mouser has something like this.

Just curious. Why the need for 500 Ohms?

Mouser sells a line of inexpensive ($1.50-3.00) small signal audio transformers in a variety of windings.
