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

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