Class B Amplifier and the Class-B Transistor Amplifier

WebIn class-C, active conduction occurs for < 180 ∘ (but more than 0 ∘ .) Anything less than class-B would be class-C. In class-AB, active conduction occurs for more than 180 ∘ but less than 360 ∘ of the period. Anything more than class-B but not fully class-A is called class-AB. The above pretty much covered all the cases (except for ... WebDec 31, 2007 · In summary: Class B amplifiers generally introduce some crossover distortion. Class AB amplifiers may introduce some crossover distortion. Class A amplifiers introduce no crossover distortion, as both valves conduct simultaneously. The solution therefore, seems to be to use Class A for guitar amplifiers.
