First Watt SIT-3 Power Amplifier

Description

The First Watt SIT-3 is a solid state, low-power fully Class A design, this one uses no feedback and it puts out 18 watts per channel into 8 ohms, and 30 watt per channel into 4 ohms.

The First Watt SIT-3 uses a Static Induction Transistor (aka VFET) in the power stage of a simple no feedback amplifier. This SIT was uniquely fabricated from Silicon Carbide with the
character of a tube Triode – acting more like a voltage controlled resistor than a current source. The primary benefit of the SIT is the much-desired audio quality of a Triode tube, and is different from ordinary FETs which have a Pentode character.
