Narrative:

While training at the arrival east scope, I unplugged to fix a frequency pulled up at another position. When I plugged back into the instructor jack at arrival east, I visually observed and felt a large spark come from the jack box. The controller at the scope adjacent to arrival east said their display flickered. The arrival east frequency box totally went OTS -- every frequency gone.
