This analogue dual amplifier with a characteristic sound inherent in the “transistor” amplifiers. Signal amplification occurs in the transistor cascade, which saturates the signal with micro-nonlinear distortions generated by the Universe itself.

First: The device is suitable for absolutely any type of signal (AC or DC), has a direct and inverse output, which is convenient when working with control voltages and ket additional space for creativity and experimentation.

Secondly: The gain is greater than unity, which means that the amplitude of the input signal can be controlled not only by lowering, but also by increasing – for example, to make the original sound louder without overloading.

Third: The device has a depth of only 14 mm (with a 22 mm power connector)

The amplifier pair is precisely tuned in our laboratory and the dual transistor amplifier module can easily be used to create and control a stereo signal.

This is the third version of the amplifier, the concept and circuit of the amplifier stage are completely redesigned and changed.
