The similar [[B9E base|B9E (Novar) base]] used by comparable American tubes has the same pin circle geometry but the tube have a diameter of only 1.02 mm (0.038"). Inserting Magnoval tubes into Novar sockets by force will widen the latter's contacts, thereby damaging the socket. | The similar [[B9E base|B9E (Novar) base]] used by comparable American tubes has the same pin circle geometry but the tube pins have a diameter of only 1.02 mm (0.038").
