Help with Grounding+Layout of Pre+SSamp Combo

[spice house]

Hello all, here is my proposed layout for my Tube pre + SS dual mono amp hybrid

(sorry for the link but I get a broken image when I use insert pic)


Each PCB has single grounding point.


Not pictured:

AC input paths to power switch and Xformers are omitted for simplicity

Isolated RCA in (+)(-) -> Volume Pot (+)(-) -> Preamp In (-)(+)

Only (+) outs from Pre would go into Ampx2
Only (+) outs from Ampx2 would go to Binding Post (+)

Binding Post (-) : Directly to star ground


This is my interpretation of a star grounding system. I'm putting it up here because I don't know if it is right! Thank You
