The only optical and electrical perfect replicas of rare, early
radio tubes, cathode ray tubes, Geissler tubes and physical demonstration tubes


Our tubes have the same electrical characteristics and operating values as the originals!


These tubes are manufactured on a semi-commercial base in a physical laboratory with modern means and thus much more reliable than the originals.

Photo shows our replica of "de Forest" double wing, double filament spherical Audion (1906).
