GENERAL DESCRIPTION OF COMPONENTS
The resistors are ¼ Watt metal type. You can either use a multimeter or the color bands to obtain their values. Resistors don’t have polarity; you can assemble them in any direction.
Electrolytic capacitors have the value printed on them. The polarity is also is marked for the negative lead, additionally the longer leg is the positive and shorter the negative. Assemble the electrolytic capacitor according with the positive polarity (+) marked in the PCB, that is, the longer leg of the capacitor is passed through the pad marked with +.
The polyester capacitors have three numbers, read as picofarads (pF), the first two are the 1st and 2nd digits and the third is the multiplier code. This type of capacitors doesn’t have polarity; you can assemble them in any direction.
The ceramic capacitors have three numbers, read as picofarads (pF), the first two are the 1st and 2nd digits and the third is the multiplier code. This type of capacitors doesn’t have polarity; you can assemble them in any direction.
Potentiometers can be mounted directly on the PCB. For a correct orientation, the potentiometer shaft is marked on the PCB.
Transistors are three terminals components and their model and name are printed on them. To indicate the correct assembling position one side of the transistor is flat and the other one is round, in the same way, the PCB is marked with round and flat side.
Diodes have their type number marked on them. This two terminals component has polarity; a ring near the side indicates the cathode. This ring is marked as a line to indicate the correct polarity in the PCB.
