First Watt F8 First Watt, April 8, 2020

Originally created almost 6 years ago, the F8 is a stereo two-stage single-ended Class A amplifier using the NOS Toshiba 2SJ74 P channel Jfets and SemiSouth R100 SiC power Jfets for signal gain, plus IRFP240 Mosfet mu-follower current sources, for a total of three devices per channel.

It is similar to the J2 amplifier, but has only one front end transistor instead of six, operated as a current feedback amplifier (CFA) as opposed to the J2’s voltage feedback (VFA) differential input. This front end is more consistent with the single-ended approach to amplifier design and yields a purer second harmonic character, less distortion with lower negative feedback, greater bandwidth and higher damping factor.

The Cosmotron project was conceived to create high quality loudspeakers that not only produce excellent sound, but are also beautiful, and exquisitely engineered. The speakers are sculptures, works of art in their own right. There is no reason why loudspeakers cannot be stunningly beautiful. It just takes a lot of time and effort, and the desire to produce as close to perfection as is reasonably possible.
