Looks like it's based around 12AX7 valves. I seem to have a fetish for clones and valve phonostages.
I wonder if this could make a good project.

Maybe, I would just love to see the Sansui phono first. Not that I know that much about Sansui history, but I'm pretty confident that from mid-70s on (when I started following them), they haven't had a separate RIAA from their integrateds/receivers.Originally Posted by REXTON

There's a plenty of functional phono DIY projects around and I would go for those based around D3a, E810F or other tubes of a rather higher industrial grade than ECCxx which may cause a plenty of issues, especially in low signal positions, due to variations from reference quality. You have a nice Thorsten Loesch LCR RIAA schematics on the net, with 600 ohm LCR network. Things can hardly get better than that.
EDIT - I see the schematics on Ebay now. I don't get what six ECC83 are for in a phono stage?!

The ECC83's are being used in the SRPP configuration in an attempt to normalise the gain and Miller capacitance, with different valve characteristics and age.
I would guess that the noise performance would be poor on MC, with valve selection needed.
Agreed.
Also, "no feedback" is rather misleading. There's feedback all over that circuit.

Yes, no 'overall' feedback is rather what I think is meant.

Will stick with the EAR clone.
