“VALVIX” Kenotron

The Müller Kenotron

                 This kenotron dates back to the forties. French made by “VARAY” who were since 1920 representatives in France for CHF Müller tubes and valves.

             During WWII, VARAY started manufacturing replacement tubes and valves, under the “TUBIX” brand.   The resemblance between this kenotron, and the Müller kenotron (see picture) is striking.

             The metal cupping at  the left end of the kenotron is the anode proper which is part of the wall of the tube and is in continuity with the glass wall. It is normally covered by the aluminium heat radiator (See pictures and x-rays of  the tube with and without the radiator).
