LINE PREAMPLIFIER

This preamplifier has 6 switchable inputs, volume control and single gain stage with 6SN7 valve in SRPP configuration. This circuit has low output impedance so the cathode follower buffer is not required. There plate voltage is stabilized by means of valve voltage regulator(also with the 6SN7). The chassis is vibration isolated. Input switching is provided by high-grade Elma rotary switch, while the volume control is based on precision ALPS potentiometer. The signal track is as simple as possible in order to minimize the sound deterioration.
