Abstract
295,330. Allgemeine Electricitõts- Ges. Aug. 9, 1927, [Convention date]. Vacuum tubes. - A multiple valve has indirectly-heated cathodes C with heaters A which are supplied with alternating current and insulated from the cathodes, the leads to the heaters being as short as possible so as to reduce capacity coupling with the other elements. The valve shown has a detector stage and a two-stage resistance-capacity coupled amplifier mounted in a single envelope.
