Remarks[edit]
The EXTRACT is a mono power amplifier from the Fuldbrück-based hi-fi manufacturer RESTEK. The EXTRACT is parallel balanced and has a cascade circuit in the input stage which drives eight output transistors via the driver stage. It can drive loudspeakers up to a minimum impedance of 2 ohms and deliver more than 400 watts.
