Audio-Hungary writes. “Many customers asked us about the possibility of a rusty design amplifier. We are happy to announce that Audio-Hungary launched a rusty design version of its Qualiton A20i.It is a unique design, devices are aged by environmental friendly technique. The rust is preserved with a special lack which stops the corrosion at the actual condition. Also it keeps the electronics from corrosion. The potentiometer is made of copper, so it fits to the device.”
