Thank you for viewing. This is a listing for a Noah'sark PTBS-1 Programmable Switcher. As shown in the images, the unit has been tested and confirmed to be working. (Please note that I have not tested it with actual effectors connected.) Also, there is a crack in the LOOP1 connection and the LOOP3 connection is missing the metal fitting. Both can still accept a cable and there is no looseness, so I don't think it will affect use. Please consider this item only if you understand that it is a used item. Thank you.
