Webthe F7 Power Amplifier Short Story Long: Conceived in 2007, the F5 was a push-pull Class A amplifier employing eight semiconductors and 23 resistors to achieve 25 watts output with good specifications and good sound. You can read about it in detail in both the owner's manual and DIY construction article, both posted at www.firstwatt.com WebApr 10, 2024 · It’s worth re-iterating here that the First Watt F8 puts out 25 watts per channel into a typical 8-. ohm load, but decreases its output to only 15 watts per channel into four ohms. Fortunately, both sets of speakers I used are nominal 8-ohm loads, so the F8 was able to give me its best power in both situations.
