Die EXTRACT ist eine Mono-Endstufe des in Fuldbrück beheimateten Hifi-Herstellers RESTEK. Die EXTRACT ist parallelsymmetrisch aufgebaut und verfügt in der Eingangsstufe über eine Kaskadenschaltung die über die Treiberstufe acht Endtransistoren ansteuert. Sie kann Lautsprecher bis zu einer Minimalimpedanz von 2 Ohm antreiben und dabei mehr als 400 Watt abgeben.
