Variants

The metal/glass Arcturus Coronet 6J7 type tube is unusual in that it employs a glass disc instead of a conventional "pinch" for introducing the lead-in wires into the glass bulb. The disc has the wires in a circular formation. Pages 99 and 100 Stokes "70 years of Radio Tubes and Valves".

6J7 painted glass tubular (GT) version from Belvu (Mazda) bulb like a 6J7V. Dimensions 103x32mm.

6J7 en triode

Le tube 6J7 en triode est une des meilleurs parmi les tubes anciens (et même modernes). Sa linéarité est remarquable. Brimar propose de se rapporter au 6C5 pour son emploi en triode… oui pour les calculs du montage, mais le 6J7 est beaucoup plus linéaire et permet un cursus nettement plus élevé sans distorsion que le 6C5.
