Hi-Fi Discrete PreAmp (Class-A)

skematiknya :

output impedance = 1.6 Ohm

Quiescent Current (max output Current Class-A) = 6mA

input noise = 13.8 nV/sqrtHz

gain = 6dB (R4/R5+1).

      yup, low noise, but I feel not quite much dynamics. maybe because it used cheap 2SK30A NJFET and 6mA only (high output impedance).
