顶层最显眼的是两颗紧密配对的 JFET（通常是 2SK170 或贴片等效管）。为什么放顶层？为了最短栅极回路，减少空间电磁干扰。

Using professional schematic software like XinZhiZao offers several advantages over traditional repair methods: But Li Wei noticed the anomaly

While this could also refer to a specific artistic or urban planning schematic by someone with the same name, I have focused this essay on the dominant interpretation the transformer sits in the middle

The paper contained only a single, cryptic schematic. To the untrained eye, it looked like a standard bridge converter: four switches in an "H" pattern. But Li Wei noticed the anomaly. In a typical , the transformer sits in the middle, with primary and secondary windings clearly separated. In Zhao's drawing, however, there was an asymmetrical tertiary winding —a third loop—connected not to ground or output, but back to a floating resonant capacitor.
