Скачать или смотреть 2 amazing idea - Diy Powerful Amplifier With One 2SA1943 Transistor | Class A

➤ Hi everyone, today I how to make two powerful (class A) amplifier circuits, using only 2SA1943 transistors.
➤ 0:11 First circuit amplifier using capacitors output
➤ 7:26 Second circuit amplifier. The speaker is connected directly DC power supply
➤ Amplifier circuits that use the 12vDC to 19vDC power source for the first circuit.
➤ And 12vDC for the second circuit (because the circuit supplies DC power directly through the speakers) but the second circuit is simpler.
