Cayn Vacuum Tube CD Player CDT-17A repair and new Project

These days I started restoring an old purchase, a Cayin CDT-17A CD player that I bought years ago for a modest price, $200. The CD player had various problems, someone had tampered with the PCB to the point that it no longer worked. I managed to "resurrect" the CD player, I asked myself the question, leave it like this or redo everything, and, how to proceed? In the absence of an electrical diagram and taking advantage of my passion for PCBs, I redesigned everything, separating the various stages, Control, Power Supply, DAC and finally the Tube power supply and audio and the digital audio outputs. The result is this. Now, is it possible to improve on the original design? Does anyone have any ideas?
On the net you can find something, but nothing of that!
