kollin Posted December 22, 2015 Report Share Posted December 22, 2015 Okay sir, I will add an external power supply for the meter.1. I really can't get a hold of these new op amps. I searched online, and found uA741CP Op amps, is it a good sub?2. Also, I was thinking of connecting the center tap like the attached image, since it's easier to get a hold of a center tap transformer in our area. Would this work? 3. Did anything change from the original schematic? I am trying to redesign the board to accommodate the updated parts list. Thanks. Quote Link to comment Share on other sites More sharing options...
