Description
The First Watt SIT-4 power amplifier uses advanced industrial Static Induction Transistors (SITs) for high-quality audio with simple Class A circuitry. Building on earlier models, it features a powerful Tokin THF51 transistor rated for 600 volts and 30 amps, enabling wide bandwidth and strong performance without output transformers. Its straightforward design relies on minimal active components, ensuring clean, precise sound with efficient heat management. Ideal for audiophiles seeking a refined, technically sophisticated amplifier.
