Clone of Accuphase C-27 (Project C-28)

Hi all,

just photos of my implementation of great Accuphase phone-stage C-27. I call it Project C-28 because it has only MC-section and there are some small changes in schematics compared with the original one. As for the sound - it`s great! Really.

I hope this may encourage someone uncertain in his forces in repeating the project and enjoy the great variety of music :)

Update 1. Schematic and gerbers can be downloaded from the following link: C-28.
Update 2. DipTrace files can be downloaded from the following link: C28_(2).

Hi there.
Watched your thread on the russian website. Nice pictures.
2 questions. Where did you source the PCB´s, did you get them made yourself, and are they available for us in the forum?? Maybe with a BOM also???
Waiting for your answer :)

1. I had to make PCBs myself because I use only MC-section of the preamp. It`s quite hard for the beginner as I am to repeat the full preamp. Yet I don`t need MM-section.
2. I can share them without any restrictions, need only to find them on my PC. As for the BOM I don`t promise it cos don`t have all in a single file, but will give references to very specific components. Guess this is not the main difficulty. Anyway ask your question here.

Regards,
Sergei.
