Простые усилители на одном транзисторе

In this video, we will assemble several audio amplifiers on one transistor at once. This is again a P210 germanium transistor, but with a slightly more complicated circuit that does not pass a constant voltage to the speaker system. Also, for comparison, we will collect circuits based on a KT819 transistor, a Chinese fake 2SD718, an amplifier on one IRFP150, and an amplifier on a KT827 composite transistor. Let's measure their output power, listen to which is louder and which is better.
