Vandrayk's Tuning Apparatus was an advanced piece of technology designed by Doctor Gorman Vandrayk. Components of the Apparatus included a four-stage resonator, a phase inverter, a submicron polarizer, a variable-flux depolarizer, a multiharmonic sequencer, and a quantum receiver. During the Grand Acquisitions Race, a Vandrayk's Tuning Apparatus was one of several items that the Chevin Conglomerate sought to acquire.
