audioguru Posted April 19, 2006 Report Share Posted April 19, 2006 You won't find a trimmer capacitor that goes down to zero pF. There are many of them that go from a few pF to 30pF or 35pF. If the tuning needs to go to a higher frequency then subtract a turn or two to the coil. If the tuning needs to go to a lower frequency then add a turn or two to the coil.www.digikey.com has many trimmer capacitors. You don't say your country in your profile so we don't know if you can shop there. Quote Link to comment Share on other sites More sharing options...
