Product details:Referring to PJ in the UK The Baxandall type electronic tube tone control circuit utilizes a low distortion tone circuit with frequency negative feedback operation, with a wide control range. Moreover, when both potentiometers are placed in the middle position, a flat response curve can be obtained.
Electronic tube preamp has many advantages, such as high input impedance, large dynamic range, low thermal noise, good transient response, low distortion, good air sensitivity, and simple circuit design.
Using 6z5p high-voltage rectification, 6p1 electronic tube as high-voltage stabilizing output, and two 12ax7b amplifiers.
