Excellent phono preamp hand built by Jim Hagerman. From Jim on the kickstarter campaign: "The Cornet3 is a radical evolution of the highly acclaimed circuit I  developed and introduced about a dozen years ago. If you are seeking top-notch electronics to bring out the best in your turntable and vinyl collection, look no further. For those of you with moving coil cartridges, I am including the Piccolo2, a re-designed active head-amp with up to 26dB gain, built into a matching enclosure...

...you would have to spend well over $2000 to get the equivalent performance from anyone else in the industry. That makes the Cornet3 and Piccolo2 incredible bargains."

The Cornet3 delivers high performance on a budget. The circuit topology features common cathode class-A gain stages with no feedback, passive equalization, and cathode follower output buffers with constant current sink loading. Power is supplied by a regulated wall-wart driving a boost converter (running at about 50kHz) to generate the high voltage rail required for proper tube biasing.
