Components mounted on this board include a potentiometer, a two stage amplifier using transistors 2N4250 and 2N4033, resistors 270 Ohms and 4700 Ohms, two capacitors 0.1 uFd, and one LED. Function of this lashup is unknown.

The veroboard has copper tracks to which the components are soldered. This is a typical early design approach before making a final printed circuit board (PCB).
