I connected a step down transformer to the input of an amplispeaker with a 50K cermet preset potentiometer to listen to the 50 Hz hum of alternating current.
Three pins of the cermet 50K preset potentiometer were placed on three rows on a solderless breadboard. Jumper wires were used to connect the terminals to a digital
Preset potentiometers are are variable resistors. The resistance value can be varied using a screwdriver to turn the screw mechanism on the device. Cermet is a combination of
Today I checked the input to the bridge rectifier from the step down transformer and the output of the bridge rectifier. As expected, there was a significant difference

There are several types of audio connectors. Most commonly used one these days is the 3.5 mm TRS connectors (Tip, Ring, Sleeve), which are stereo pins. Corresponding mono
I used four rectifier diodes and a 1000 MFD filter capacitor to assemble a simple bridge rectifier on a breadboard. Used jumper wires of red and black colour
