Audio preamplifier based on the NE5532 chip. It is powered with the voltage from 9 V to 35 V (does not require symmetrical voltage). It serves as an element pre-amplifying the low amplitude signal in the audio path. The integrated circuit is placed in a socket, so it can be easily replaced with a new one in case of damage.
