Low_cost_high_level_preamp_and_tone_control

This circuit uses the JFET to best advantage (low impedance). All device parameters are non-critical, yet the circuit achieves harmonic distortion of less than 0.05% with a S/N ratio of over 85 dB. The tone controls allow 18-dB of cut and boost. The amplifier has a 1-V output for 100-mV input at maximum level.
