[sdiy] Inverting/noninverting attenuator circuit

[René Schmitz]

Hi all,

Here is a circuit that I occasionally posted here before which does 
this. You can add a second trimmer between the two 10k pots to adjust 
the position of the dead spot.
If I'm not mistaken this is what was the inspiration for Peter Grenaders 
version, I remember discussing it with him the last time I posted it.

Cheers,
  René
