Aleph 30 the best choice of C1 C2 C3 on brian gt PCB

[wengtech]

i am following this psu schematics :


this is the worse psu i ever tried!!!
very very big distortion, noise, and hum....

nothing wrong electrically with it , but physically you need to make it completely opposite

star gnd must be positioned exactly between C14 and C15 (for R channel) and exactly between C16 and C17 (for L channel)

besides that , you need to make a bridge with fat wire between these two points

it's much better having two bridges config - Papa explained reasons for that (avoiding any possibility that nonsymmetrical load induce buzz in windings) ....... and - if having two (per channel dedicated) C banks , then is best that each bank have own 2 bridges

that way one can have almost dual mono approach , without need for mentioned fat wire between two central grounds

exactly zen mod,
star ground located at transformers CT or between two bridge diodes was a real bad idea...

i am trying some psu schematics, but no one can real eliminates hum and hiss,
do you have one reliable psu schematics?

Do you think you could make those tiny, postage-stamp sized images somewhat larger?
