Looking good! I can’t see your grounding scheme from the photos but isolating the power supply grounds from the input/preamp side will help keep the amp quiet. Run the grounds from the filter caps to the power supply side of the chassis, maybe to a lug on one of the power transformer mounting screws. And the preamp grounds together on the brass grounding plate or buss bar.
