Re: Noise issue with DIY variable PSU and audio amplifier
[QUOTE=G6ONEDave;1519769]I've attached my thoughts on a circuit for you that might do the job.
Thanks for the detailed analysis and the circuit diagram. I think my UPC1212C IC has survived my experiments so far as the amplifier circuit still works normally when powered from another external source.
I will try to modify my circuit based on your diagram or else build a completely new one.
