This is the schematic..

This is my first board...
There are two ground wires (each one carries the grouped grounds of driver and final stage) wich are connected on the second supply capacitor..

This is my new wiring.. Grounds are connected on the first capacitor (right after rectifier bridge)..
--->Wich one do you think is right?

What do you think about the cathode's circuit? (inside the red line)
Up to now i dont see or hear any difference. Noise remains low.

Testing...
