[sdiy] simple schematic to convert line level signal to phono

[René Schmitz]

Hi Peter,

on a quick google search this here surfaced:
http://www.jensen-transformers.com/as/as071.pdf

I've seen such a circuit in one issue of elektor it was 
basically the same, just without the transformer. So you 
should get away with one.

Cheers,
 René
