What is best, a ready-built rectifier bridge or one built from discrete rectifier diodes?
You can find arguments for both actually. Some say that the diodes in ready-built bridges are more closely matched than individual diodes and are therefore superior. Others will point out that using individual diodes allows you to use better, (faster, soft recovery) diodes. For absolute beginners, a ready built bridge is one less part of the circuit to construct and get wrong. It will come with four connectors and clearly marked showing what wires to connect where. One rated at 15 amps or more will be more than adequate! Take your pick!
