This amplifier consists of Uniamp power amplifier, Unipreamp, acoustic spectrum analyzer and other systems.
Housing:
Housing was made of plexiglass with a protection against overheating in the form of smooth hardboard, which is visible from the inside. Plexglass was cut into rectangles with grooves in the base and cover for the rear and front panel and transparent sides. White plexiglass was painted black. The housing stands on rubber feet.
Uniamp power amplifier:
The construction of the power amplifier is well known. It uses Nichicon capacitors, 10.000uF Panasonics. The PCB was made in thermal transfer method. 2X32V 250VA transformer supplies it.
Unipreamp:
The Unipreamp has a correction of bass and treble, balance and volume.
Acoustic spectrum analyzer:
It uses blue LCD display so it looks nice together with the lighting. It provides dynamic to the amplifier.
Lighting:
The amplifier is equipped with 7 blue microdiodes connected in series. They are supplied from a transformer 12V 20VA and additionally there is a voltage doubler. There is also a knob next to the fuse in the rear panel, using which you can change the lighting (increase, decrease or even turn it off). The knob is backlit by a diode in a thin plexiglass in a shape of ring. After turning off the amplifier, the lighting dims.
