Description
First Watt F7 Power AmplifierThe F7 is a 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. The F7 is now in production. Here is a link to the first of many reviews: F7 at 6moons

Epson ink
Style: Ink
The EPSON 812 DURABrite Ultra Ink is excellent! It fit perfectly in my printer with no problems at all. The print quality looks sharp, clear, and professional colors come out bright and crisp every time. The ink lasts a long time, so it’s definitely worth the price. I’m very happy with it and will definitely buy again. Great product from Epson!
