  • Patent number: 9515616
    Abstract: Tube amplifier system including a plurality of conductor walls extending parallel to a longitudinal axis and defining an interior space therebetween. The tube amplifier system also including a shorting deck that extends transverse to the longitudinal axis. The shorting deck is electrically coupled to the conductor walls. The tube amplifier system also includes a movable tray assembly having a grounding deck that extends parallel to the shorting deck. The grounding deck and the shorting deck define an output cavity therebetween that has a length. The movable tray assembly is removably mounted to at least one of the conductor walls such that the grounding deck is capable of being positioned at multiple different levels along the longitudinal axis to change the length of the output cavity.
