My friend has just shared a circuit for his Marantz 7's phono section project.

I will follow this, once I complete the line section, I'll come to that later.

I could never get past the mountain of coupling and cathode bypass caps in this design. That's why I built my own based on the RCA. No cathode caps and only two for coupling. I would also never use a 12AX7 for output duty, especially in a standalone preamp. It's simply too limited. Not trying to rain on this parade, but I do think the best years of this product are behind it.

  I take a look into the most earliest Marantz preamp, the audio Consolette, its phono section seems less complex.
  
  My friend told me it sounds better than the 7 by comparison.
  
  What do you think 🤔
