<pre>Ken said:<br></pre><div style="margin-left: 40px;">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.<br>
All I've been able to find is insanely expensive, like US$200.<br>...<br>But my searches (Jameco, Mouser, DigiKey) aren't turning up anything except POWER transformers, much larger than what I need.<br>Can anyone point me to some part numbers and (reasonable) prices for a 1:1 line level transformer?<br>
</div><br>When you say line level transformer it will lead you to power (line level) transformers.<br>I did a search for audio transformers at Mouser and came up with over 100, <br>some of the pulse brand 1:1 transformers looked like they would do the job in the $3 to $12 range for single items.<br>
You need to figure out what impedance you what, 50 ohm would probably match ipod ear buds.<br>Good luck.<br> <br><pre></pre>
