A vintage example of a tool that starts off with such an assumption is undoubtedly an analog audio electric power amplifier designed in or before the early 1970s, or a far more modern-day piece made along precisely the same traces. Linear regulation throws off excessive heat to be simple in this kind of a device, low-noise switching regulation engineering wasn't seriously readily available at time, and so amps of that time had been developed with generally unregulated energy immediately driving the amplification phases.
