1k might be too low and overload your source, again industry standard is 10K. Also use a 10 to 100uF cap on the half supply to pin 3 also 10K resistors are fine here.

Just for info i use this as a virtual earth input buffer on my Camm EquiTone preamp with gain set at about 2. Works well with the TA7630p that follows, better than any tone control.

<quote>The LM741 circuit and the tone adjust circuit are taken from some audio website.</quote>

WRONG! The second circuit was stolen from my site ( sound.westhost.com ) and is reproduced here without permission.

Moderator - please remove the image from my site from this thread - I am sick and tired of people stealing my drawings without permission or even the common courtesy of acknowledgement.
