Guest 78L05 Posted July 13, 2013 Report Share Posted July 13, 2013 I drew my own PCB design based on original schematic (with 3 TL081), and I will be very happy if I could fix it without major changes.I tried to put 27k for R10, but the same thing hapeens. I didn't touch trimmer (it's now 100k). When I remove the capacitor on the output (C7) voltage is about - 0.15V. I put tantal capacitor at the same place but voltage is again about - 0.35V (like the first time).What to do? Quote Link to comment Share on other sites More sharing options...
