Sparkz C3

The Ansuz Sparkz C3 is a mains-socket noise-reduction device made by Ansuz, designed to plug into unused mains sockets. It uses a Bakelite housing, one Gold Anti-Aerial Resonance Coil, one zirconium bar, silver/gold-layered copper coils, and third-generation analog dither technology. Its active Tesla-coil topology uses two oppositely wound coils—a regular spiral and its mirrored counterpart—to generate counter-surges against voltage spikes; dimensions are 39.4 × 71.2 mm (1.55 × 2.80 inches).
