One S2001 and one 2E26, for a total of two tubes. The manufacturer of the S2001 is Matsushita, and the 2E26 is TEN. I do not have any equipment that uses these vacuum tubes at the time of listing, so I have not been able to confirm their operation in a device at the time of listing, but I have confirmed heater continuity. There are no boxes. I plan to send them via Takkyubin Compact, but I may change to Yu-Yu (anonymous delivery). The S2001 is for use as a spare tube for the TS520, FT101 series, etc., and the 2E26 is for use as a spare tube for the SKA6, etc. Please consider them. # Transmitting tube amateur radio 6146 final stage
