Class A circuitry

Class A circuitry refers to an amplifier design where the output device (such as a transistor or tube) conducts current throughout the entire input signal cycle. This means the device is always active, providing very accurate and low-distortion sound or signal. While it offers high fidelity, Class A amplifiers tend to generate more heat and are less efficient because they continuously draw power, even when there's no input signal. They are favored in high-quality audio applications where sound accuracy is prioritized over efficiency.
