Nέος ενισχυτής απο τον Nelson Pass και μερικά σχόλια για τη συνεισφορά του στη DIY κοινότητα.
"Nelson Pass, America's preeminent designer of transistor amps, invites us to consider with his newest FirstWatt power amplifier. The F4 is that rare amp whose X factor is zero. It's minus 0.5dB in fact. Hence it doesn't really amplify. But it most certainly conditions the signal.
That conditioning action makes the F4 a power buffer or Class A impedance converting amplifier - no voltage gain, no feedback.
...
FirstWatt is obviously subsidized by Pass Labs. The latter affords Mr. Pass the leisure and economic freedom to run FirstWatt as a turnkey DIY venture rather than assembly-line operation. Creativity is king. Plus, Nelson is very hands-on through the Pass page at DIYAudio. A dedicated thread has been growing there ever since rumors of the F4's imminent release first surfaced. And unlike with earlier FirstWatt models, the full circuit schematic for the F4 has already been published."
