Read MoreModBlog – MosFet vs BJT Transistors
Solid state amplifiers, all use BJT or Mosfet power transistors at their outputs, including Class D designs. The purpose of the transistor in this case is to buffer current into low impedance speaker loads. So, which transistor should we use and how do they differ in sound? The two basic choices are Mosfets (Metal-Oxide Semiconductor…
