audioguru Posted May 25, 2005 Report Share Posted May 25, 2005 Hi Divljo,I think your current regulator and Q1 should work with the 7805 and 7905 regulators and R23 and R24 removed. The fairly high DVM display current is overloading the negative 5.6V supply.You can power the DVM regulators with a separate transformer, rectifiers and filters. The current adjustment comparator, U3 needs the 5.6V negative supply. ;D Quote Link to comment Share on other sites More sharing options...
