[apelizzo]

Is there any schematic available for viewing?
- Power supply
- Pre board

Thanks

 

[tangmonster]

This is the main project web page:

Hi-end phono preamplifier

it has schematics.

 

[apelizzo]

This is the main project web page:

Hi-end phono preamplifier

it has schematics.

Is that the power supply used in this project???? Should it be Salas shunt?

To get a better performances I will try a different RIAA network near to the design used in my Phono End.

The new RIAA, like Audionote, will use silver mica capacitors instead of Wima MKP.

To use silver mica it is necessary use little capacitor value so the resitors will increase the value.

This also allow to use better quality interstage capacitors with littel value 0.22uF and 1uF instead of 2.2uF Wima.
