Mohon Menunggu Package : Yes Channels : 2 (2.0) Model Number : PASS PCF F7 Maximum Power Per Channel : 20W Certification : NONE Introduction: FirstWatt F7 is a very good small class A amplifier, with almost no advantage of feedback brute force. It resorts to a strategy that makes the dance a bit more like tango. Appropriate amount of negative feedback and positive current feedback form a balanced impedance close to zero in the output, which improves the transient response and frequency response. Of course, you can achieve a similar effect by using a lot of negative feedback, but I think this is more elegant and sounds better! For the sake of brevity, I willit #34;PCF #34;. We used more filter capacitors in the power supply and found a clever way to further reduce the effects of high frequency DAC noise and ambient RF. FirstWatt F7 This is a different amp. Variety of audio tastes, not everyone will like it. I think some audiophiles will like it. Adopt all-aluminum double heat sink chassis, Class A power amplifier needs enough heat sink. The appearance is also very beautiful. Customized 300W OFC pure copper transformer with iron core imported from Japan. Low noise. The power board adopts Schottky MBR60200PT as CRC fast rectifier, which is the favorite rectifier tube of Class A amplifier. It uses Nichicon 22000uF/35V X 8large audio filter capacitor, and the powerful filtering power brings you a different enjoyment of listening to music. With SPK protection function to protect your speakers. Adopt CANARE signal input wire, output use UK PRYSMIAN pure copper wire. According to the circuit characteristics, K170 and J74 input tubes are precisely matched, and the output MOSFET power tubes are EXICON ECX10N20/ECX10P20. (Old audiophiles know that EXICON MOSFET ECX10N20/ECX10P20 is often used in HI-END luxury amplifiers, and it
