Description

Late in 1926 Cossor introduced their new Kalenised filament. Exactly what the Kalenising process was they did not state, making only the modest claim that it "gives off a torrent of electrons partically without heat". This filament was used in the Cossor Point One, 210D and 210H valves, and also in a power valve denoted only as the Stentor Two, to which the number 215P was later assigned.
