Amplifier "Reaktor Nummer Vier" project name carries some memories from the past. Amp itself is boosted by a modern  components and technical solutions.
This amplifier acts as a good example how it is possible to manage a well sounding device with only three transistors applied operating in class-A.
The amplifier is usable as a power amplifier or stand alone due to inner volume potentiometer.
VFD output indicator gives a nice retro visual touch.
