not enough room here to use IC sockets. Bend the pins against the foil to save room Photo B shows the completed readout board with attached cable At this point you have two boards connected by a multi-conductor cable. Plunk this assembly back in the hiding place.

Power Supply

This part is as easy as getting a CB license. To avoid overworking the built-in power supply, 1 mounted the three-terminal regulator on the Heath Z-shaped chassis near the mike cable clamp. (I used a

mike connector and moved

it to the right side of the front panel, but this is not necessary ) Run a wire between the input terminal of

the regulator and the 13.8-volt supply, and that's done.


It's time to dig out the circuit boards from their hiding place one last time and wrap up the project. Depending on how ambitious you are, you can make a mounting bracket for the driver board, or if you're as lazy as I am, just wrap the board with tape and slide it alongside the speaker, between the magnet and chassis. Stick a hunk of tape to the foit of the readout board to insulate it, and thread the readout board and cable over to the meter. Wedge it between the meter and vco
