First Watt SIT-5
Image source — © First Watt
The First Watt SIT-5 monoblock uses the same type of output transistor, but it is configured in a Common-Drain circuit, i.e., effectively in the source follower mode. A complementary push‑pull voltage amplification stage operates before it, while the output section remains predominantly single‑ended and operates in class A without negative feedback.
