Front panel added in standard to the kit was modified a little. The front panel board was designed so the left channel is a mirror image of the right one. Visually it looks better than a one next to the second in the same order. 10 frequencies are on the channel, starting from the inside they are: 32Hz 62Hz 125Hz 250Hz 500Hz 1kHz 2kHz 4kHz 8kHz 16kHz. The board with the displays is one-sided, after soldering the parts, connect the diode cathodes using a wire, just like in the picture.
