: Swapping the factory BJT switches in the current sense circuit for MOSFETs like the 2N7000 for better linearity.

: Precision operational amplifiers compare the output voltage and current against the levels set by the front-panel potentiometers, adjusting the pass transistors to maintain a Constant Voltage (CV) or Constant Current (CC) state. Common Components in the Schematic Yh-305d Power Supply Schematic

The YH-305D's narrative includes frequent user reports of quality control issues, particularly with overheating. Many hobbyists choose to modify their units by: : Swapping the factory BJT switches in the
