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.
Claims20
A tube amplifier system comprising:
- a plurality of conductor walls extending parallel to a longitudinal axis and defining an interior space therebetween;
- a shorting deck extending transverse to the longitudinal axis, the shorting deck being mechanically and electrically coupled to the conductor walls;
- and
- a movable tray assembly including a grounding deck that extends parallel to the shorting deck, the grounding deck and the shorting deck defining an output cavity therebetween that has a length measured along the longitudinal axis, the movable tray assembly being 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.
A movable tray assembly configured to form part of a tube amplifier system, the movable tray assembly comprising:
- a grounding deck having an input side and an output side that face in opposite directions;
- a ground wall extending away from the input side of the grounding deck;
- and
- a shorting deck extending parallel to the grounding deck, the ground wall extending between and mechanically and electrically coupling the grounding deck and the shorting deck, wherein the grounding deck, the ground wall, and the shorting deck define an input cavity, wherein the grounding deck, the ground wall, and the shorting deck are configured to have fixed positions with respect to one another and move as a unit when the movable tray assembly is moved for positioning with respect to the tube amplifier system.
A tuning capacitor assembly comprising:
- a connector wall surrounding a central axis and defining a thru-hole that is configured to receive a power tube, the connector wall having an inner side that faces inward toward the central axis and an outer side that faces outward away from the central axis;
- and
- a tuning sheet surrounding the central axis and interfacing with the connector wall, the tuning sheet having an inner side that faces inward toward the central axis and an outer side that faces outward away from the central axis, wherein the outer sides of the connector wall and the tuning sheet form a combined capacitive surface, the tuning sheet being movable along the central axis to change a size of the combined capacitive surface and adjust an amount of capacitance provided by the tuning capacitor assembly.
