1168 HANDBOOK OF PROJECTION FOR Figure 426. IMPORTANT.— This is a side view of the main amplifier shown in Fig. 425, with one side of its casing removed. In order to make a picture with less reduction I have cut the photograph in half. As a matter of fact the part at the left is the top part of the amplifier and normally sits on the part at the right. Fig. 427 shows interior view of fader with cover removed. The main parts are disclosed to view. Each of the round buttons represents a short coil of resistance wire immediately behind it and connected therewith. The round belt connects the fader with a "dummy" located in front of the projectionist when he is in working position beside the other projector.
