This is the Solo chamber, which was the first one to be converted. This was the beginning of the swell shade project. This picture was taken from the catwalk in the tone chute outside the chambers. Most of the shutters from the right set have been removed. The wood trough along the bottom of the shutter assemblies holds the wiring for all the chambers. The trough and the wall immediately below it will be removed so the shutters may go all the way down to the chamber floor. At the far right of the wood trough you can see the end of the conduit which carries all the wiring into the relay room. The vertical wind lines at each end of the picture were connected to the two halves of the Marimba/Harp. Al Sefl is wondering just what he has gotten himself into.
