F7
The F7 is a very unique power amplifier, a two-stage push-pull JFET/MOSFET topology with fewer parts than any First Watt amplifier to date and incorporating a very interesting balance of very low negative voltage feedback and a little bit of positive current feedback to give an astonishing measure of control over reactive loudspeaker loads.
Features
- Class A Operation: The F7 is designed to operate in Class A, known for its purity and minimal distortion.
- Output Power: Delivers 20 watts per channel into 8 ohms and 30 watts per channel into 4 ohms.
- Frequency Response: Wide bandwidth, with -3dB at 100kHz.
- Topology: Uses a two-stage push-pull JFET/MOSFET design.
- Feedback: A combination of low negative voltage and positive current feedback for improved control over reactive speaker loads.
- Input Impedance: 10k ohms.
- Gain: 14dB.
- Damping Factor: Greater than 100.
- Simplified Circuit: Fewer parts than previous First Watt amplifiers.
- Sound Characteristics: Known for its textural sweetness, warm tonality, and high-resolution sound.
- Dimensions and Weight: Approximately 17" x 5.5" x 15" and 26 lbs.
- Price: $3000.
