This double triode is a Special Quality valve. It was designed for long life (typically 10,000 Hrs and/or 70 percent of new specs), reliability and with close tolerances.
It was used in valve computers, probably as a long-tailed pair (cathodes connected together, with common cathode resistor), or in multivibrator circuits.
Hi-fi enthusiasts use them as drivers for output valves. They are less suitable as pre-amplifier stages.
