Xin Zhi Zhao Schematic Top File

When Li Wei built the circuit, she observed three distinct operational modes, each a direct result of the schematic’s unique layout:

在DIY发烧圈，“辛之声”(Xin Zhi Zhao) 是一个绕不开的名字，尤其是其便携耳放系列。今天我们不谈玄学，直接用工程视角，剖析其经典机型的 Schematic Top（原理图顶层设计）。 xin zhi zhao schematic top

When searching for a "Xin Zhi Zhao schematic top," you cannot ignore the power supply, as it appears at the top of most physical schematics. XZZ famously utilized a hybrid bridge rectifier (two vacuum tubes and two silicon diodes) for the high-voltage plate supply (950V to 1050V DC). When Li Wei built the circuit, she observed
