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.
