“Machlett” ML-26 and ML-?E Kenotrons
Ref. G2
With lengths of 24” and 14” (60 cm and 35 cm), these respectively air-cooled and oil-immersed kenotrons date probably to the thirties or early forties. They have an extremely similar internal structure, and the specifications on the partly obliterated labels seem closely similar.
On the other hand, the oil-immersed kenotron (ML-?E) is close in size and conception to the Siemens V140/8G.
