my OBH-8SE

This is my version of Alexei Nikitins OBH-8SE - JFET SRPP preamp. I made a few changes - some electrolytic capacitors replaced with poly caps and input capacitor to ground was removed. This phono preamp sounds very good.
I use a DIN input because i do not want to remake the old original LP player.

  • Very nice. Simple and/but beautiful.

  • Hi Oscar,

    It's superbly constructed and very neatly done. Can you email me the schematics and few tips on doing it DIY.

    I want to make it. How much did it cost you in dollar terms?

  • Hi,
    It will not be very expensive. For me, it cost around 60 USD + - without exotic components (simple ALU box ; small transformer; BC and J113 transistors and standard capacitors)
