Default Looking for digital attenuator design.....

Last week I printed out a nice simple sesign for a fully balanced digitally controled attenuator and low and behold I came back to get the rest of the design to build but can't find where it was. Unfortunately my print out of the PDF schematic won't even allow me to read the IC types which I believe are 7400LS type.
It was a very simple design that consisted of 4 driver IC's, a counter IC and encoder. Its not the one that Jen posted. There were links to the guys site that had the board layouts, schematics, etc that I need. Did searches for attenuatopr, digital attenuator, etc....just can't seem to find it. Thanks in advance to the one that can lead me to it.

Mark

Hi Mark,

if you've found the link or the posting can you email it to me or reply this posting here? I'm looking for a digital controlled attenuator too.

ThanX,

Marc
