Electrolytic Capacitors You find electrolytic capacitors in the power supply and decoupling of valves in Hifi and guitar amps. They are like a battery because they have a positive and negative terminal. In you amp power supply they can have values of 22 up to 200 or more uF ( uF= micro-farads). Electrolytic capacitors store energy, and often they are working at voltages of 500 volts DC ! When you switch off your amp , they […]
Resistors in Your Amp This is a longer than usual article talking about the different type of resistors in your amp. Resistor technology has changed over the decades . What is common is that many types change their values over time. They usually go high in value and with certain types heat makes the problem worse. Some create noise. The overall result is that the values can change so much that the amp stops dead
