Hi,
Sorry,Did you mean an 100k input resistor on the in the inverting input of the second stage after the C=0-33uf cap? Ahhhh! now I see where I've gone wrong!! Yes, it does make sense! Thank you so much for pointing this out! I think I'd keep the gain as low as possible,say to 3dB at the most in the second stage.So by using a 47k input resistor in series in the feedback loop should give me gain of 2 then? So, what value should I use for the VR1 pot? Would a lower value ie:10k preferable to,say 100k?
