For your consideration we have an MIT Z-Strip in very good physical condition and excellent working condition. We obtained this unit when purchasing a monster system and the previous owner raved about this unit and the MIT Z-1 Stabilizer that we also have for sale.
From MIT
The Z-Strip is a 15-amp power strip that has complementary patent-pending Z circuitry, providing increased high-frequency performance in your audio system, and a reduction in RF/digital and video-frequency noise in your video system. It is constructed of the highest reliability industrial ("Hospital") grade components, indicated by the green dots on the plug and on each double outlet. This is the mark of the highest quality AC power parts available, protecting your audio/video components from such problems as contact distortion and intermittence.
Plug all your audio or video equipment (including the Z-1 and Z-2 available for purchase separately) into the Z-strip.
The Z-Strip can be placed on the floor or on a shelf, on its base or on its side. It is for indoor use only.
