Re: Noise issue with DIY variable PSU and audio amplifier
Hello Jolly7.
What kind of noise are you getting? I’m betting it’s a buzz or hum.
We’ll probably need to know how the circuits are connected to the transformers, along with the associated rectification arrangements.
I can see the secondary windings of your transformer are connected in series, but without knowing where the wires leading from them go to we can’t really help.
