Прекрасно звучащий, недорогой фонокорректор Fosi Audio BOX X2, в отличном рабочем и косметическом состоянии. Оригинальная упаковка, лампы, и мануал в наличии. Был проведён апгрейд, в виде замены оригинальных ламп на винтажные General Electric (GE) JAN 5654W (подобранная пара), из американской конторы Riverstone Audio Company.
"Only the best tubes are selected by Riverstone Audio for use as matched pairs. The mil-spec General Electric (GE) JAN 5654W was originally designed as a premium-grade substitute for 6AK5 and EF95 vacuum tubes. The "W" designation refers to ruggedized, military grade, tubes; better quality control and internal design changes to enhance reliability. This great sounding vintage tube has found new life as a premium replacement for 6J1, 6J1P, 6AK5 and EF95 tubes used in headphone and other audio amplifiers and is often used by amplifier designer's and tube roller's looking for improved sound quality. At Riverstone Audio, we personally inspect, test and pair these vacuum tubes for both plate current and mutual conductance. As a final step, prior to shipping, all tube sets are also subjected to an audio test in a preamplifier."
С оригинальными лампами, фонокорректор уже отлично звучал, но с винтажными зазвучал намного лучше.
