Below is the present GND layout.

Now I have a superlative Phono replay system.

Nice clean drawing. Very informative for those to build in the future.

So as the master tweaker of this thread

, you recommend up to now, a heavy toroid (how many VA is yours?), 2 fast bridges (what you use?) 2 shunts, wiring as in the posted zip, for guaranteed non hum infested, expertly voiced sound reproduction. Parts choices as shown in the most recent picure I guess.

PS Salas shunt for amp drive stage

Depends on how the rest of your amp will be grounded.

or live the in place the 0 caps on pcb star as now without the shunt ?

Salas all system without gnd

I would connect the filter gnds as shown from EB, then only +/- to shunts, then one ground wire from pos, and another ground wire from neg shunt to central star.
