Kuuki Ninja




 Have you heard the Kuuki Ninja?

 The answer should be no , because the Kuuki Ninja is only one product
that I made.


  FOSTEX FF85K





  Box design




   Amplifier

  Original new circuit



  Power supply is allowed to be any voltage, because final emitter voltage
comes at middle of Vcc. Ham noise is extremely low, because power entrances
have very high impedance.




  Vcc=20V

   frequency response


 Look at the pink line , you'll see low noise character of this circuit.




  Compatible with FE83, FE87 , FE83E
