Input stage is JFET having high input impedance and low noise. Circuit parameters are not critical, yet harmonic distortion level is less than 0.05% and S/N ratio is over 85 dB. Tone controls allow 18 dB of cut and boost. Input of 100 mV gives 1-V output at maximum level. Identical preamp is used for other stereo channel.- FET Data-book, National Semiconductor, Santa Clara, CA, 1977, p 6-26-6-36.
