Philips kenotron, made in The shorter kenotron 7” (17.5 cms) long, seen in the picture top right, is a physically identical kenotron, (without the end metal parts), dating probably to the fifties, German made by CHF Müller (Philips owned).

As from the seventies kenotrons started disappearing in favour
of solid state semiconductor rectifiers. Certain manufacturers even made such
replacement rectifiers in a size to fit exactly the place of kenotrons in high tension generators of their make. |
