Help?

Hi,

You might like to have a look at:

for some pointers.

:)

One general rule-- every op amp input has to have a dc bias path. The positive input does not.

And what could be a good bias point, the junction of the two 10K resistors, does not go to any dc path-- it dead ends at the two capacitors.

Methinks you need to look over the schematic again, those two points need to be connected somehow.

Thanks!

Yea, I forgot the bias and a cap to stiffen up the 1/2 Vcc rail.

Now if I could only figure out how to "adjust" a pot

Double click on the pot symbol and enter a "K" value between 1 and 0 where: 0 => slider or tap of pot at bottom (fully anticlockwise?) 1 => slider or tap of pot at top (fully clockwise?)
