6N7S x 2pcs = 1 LOT NEW NOS FOTON Vacuum tubes
A pair of matched 6N7S triodes. The difference between the anode currents and the slope of the characteristic is no more than 15 percent. All radio tubes are from the 60-70s. Pairs of radio tubes are selected that are visually identical in size and shape of the bulb and base.
6N7S double triode with an indirect oxide cathode, in glass design, designed to amplify low frequency voltage.
Tube is tested with professional tube Tester L3-3
