One of the objectives of the receiver design was to make it as simple to construct as possible, and to this end the conventional panel-and-cabinet construction was eliminated by using a dial (Millen 10035) that is easy to mount on one side of the 8 x 12 x 3-inch chassis. Aluminum chassis vary with the manufacturer; in the interests of maximum mechanical strength a chassis with welded corner gusset plates (Premier ACH-430) was used. The dial is held to the chassis by three 6-32 screws and the gain and audio controls. If the dial-drive action is stiff, it can he freed some-what by carefully prying the "crimp" drive with a heavy screwdriver blade. The most exacting job in the construction of the receiver is the mounting of the tuning capacitor, C4.

It is supported by a three-sided bracket fashioned from scrap aluminum, and it should be carefully aligned with the dial to minimize the torque requirements of the dial. The specified capacitor is one requiring relatively low torque, and its use is recommended over some of the "stiffer" capacitors of the same range. A National TPB bushing mounted near the end of the stator support bar carries the stator connection through the chassis.

The location of most of the components can be determined from the photographs. An L-shaped bracket that supports the b.f.o. tuning capacitor, C7, is the only other bit of metal fabrication other than the bracket mentioned above and the drilling and punching of the chassis.
