Yep, I cut it off to install wires from the DAC to a transformer output once. The only snag was it's not directly under the DAC so I had to use a cutting tool to extend the hole a bit!

I also cut that plate so I could reach the decoder without dismantling everything.

Now it is fixed with tape

Done some work and the screws are OK.

I aslo update the pics from my very first CD53 here : Marantz CD63 & CD67 mods list and it explains why I don't want to mess with the PCB handling

Next steps: super regs (same as the red PCBs) for the DOS, wich wll be in CFP mode, a single super reg for both sides of the DOS, my only concern is the distance from the regs to DOS and noise pick up... should be better than LM317 anyway, no? Then maybe a R core TX for the DOS... a final good MKP cap and here we go for years!

Nice work Matthieu.

You could always mount some small TL431 shunt regs directly to the dos board if the main regs are a long ways off. They're really easy to build on veroboard and tiny too.

Cheers, Lee.
