Step 9Construction: Layout
The entirety of the construction is done by soldering adjacent pads on the bottoms of the PCBs, using wire on the top if necessary.
Each board has a long trace along the top and bottom. The top is connected to the 12V power supply, while the bottom is connected to ground.
Every bandwidth occupies a vertical strip of PCB, with, from top to bottom, the filter, AC to DC, Log to Lin, and Display circuits. The nixie tubes are then attached to the bottom of the board, where they can be mounted.
Each band takes up about one-fifth of the space on the board, so the left and right boards each have 5 bands, while the middle board has two bands on the left, two on the right, and circuitry common to both the left and the right channel are shared in the middle fifth of the board.
The middle segment has the audio input jack, the amplification for the left and right channels, the 6V power, and the voltage divider for all of the log-to-lin circuits.
