In terms of power supply, a double-bridge power supply is used, that is, the positive and negative power supplies are separately rectified and filtered, and the suspended grounding method is used for power supply . The first half of the circuit
uses high-voltage power supply, and the second half uses low-voltage power supply . Separating the front and rear stages is beneficial to reducing mutual influence, reducing
hum, and improving the signal-to-noise ratio. Its power supply and protection circuit are shown in Figure 244.
