Class a vs class b circuits

WebJul 19, 2024 · A class AB circuit solves the crossover distortion problem by having two (or four) tubes overlap responsibilities. Each tube, or each pair of tubes, carries more than half of the 360-degree signal of the sine wave. In a class AB circuit, two power tubes share the responsibility of conducting the sine wave, similar to class B, but with some overlap. Webthan a Class B device. The price delta between Class A and Class B varies from vendor to vendor. However, roughly speaking, one can expect to pay about 30% more for a Class A device than a Class B with similar RF output power. Setup – The Class B device may be easier to setup because it has fewer options. For example, some Class B devices may
