RE: How to connect LL2733 for choke input

Posted by KevinC on November 6, 2016 at 15:42:09:
It is possible. Looking at the bottom diagram on the data sheet, "remove" the capacitor that follows the rectifier to give you a choke input diagram. Connect the audio circuit ground to the - terminal of the capacitor following the choke and the high voltage supply + to the + terminal of that same capacitor.
