With the latch components installed on the bottom and top shell pieces, place the top on the
bottom and test the latches to assure they are working properly. The next photo shows how the
case will look if the latches are installed correctly.
Put the completed case aside for now. It will be used again shortly, but next, the front panel will receive
its controls and then be wired to the PCB. After that, the PCB will be installed in the case and the front
panel screwed into place.
Front Panel Assembly
In the next steps, the controls for the front panel will be installed, the front panel controls wired, and
the PCB and front panel installed into the bottom shell.

Before the Volume control (R80-marked as A10K) and RF Gain control (R77-marked as A1K)
potentiometers are installed into the front panel, their shafts need to be shortened by 7/32 inch. Mark
the shaft on each, hold the shaft in a vise, and cut the shaft to length with a fine-tooth hack saw. After
making the cut, clean up the end of the shaft with a small mill file.
The next photo shows a modified potentiometer (lower) compared to one that is unaltered (upper).
