often need Amateurs with a passion for designing low-frequency amplifiers. But in the sale they are not always. The solution? To make a simple potentiometer with taps. For this it is necessary to remove the cover and remove the axle with the slider. Then with an awl to puncture the plastic covering the hole in the base. The output is cut from tinplate, it can be used from a defective variable resistor. It now remains to attach additional insights with copper rivets or cut the flare of the tube, placing the pre-side of the graphite layer is a thin metal washer (for best contact), and re-assemble the potentiometer.
