Thanks Skunky. I am grateful to you for the work done and the beautiful videos. Domenico

I've finally finished assembling Stephe's schematic and the sound is much better than the initial Sunaudio schematic, and the power and distortion too. As I said I am a beginner so I ask a stupid question: I have a slight but annoying hum that I can eliminate with the two Bourns pots. Do the two pots have to be set the same? If so, at what points should I measure the values? If I change with the Bourns, does it also change the bias? Thank you very much

Marvelous ! really beautiful.

@Skunkie Thanks Skunkie

i am trying to make a pcb without the power section which i will point to point. Did I make any mistakes? Thanks

With 230Vac I should raise the voltage with the voltage divider about 75Vdc and not 50Vdc. So I have to change the voltage divider values of the schematic. Right ?

thank you very much ️

ok thanks Stephe. The central cable of the transformer goes to the B + of the main Edcor transformer. Correct?
