With four preamps in the current AVA lineup, I welcomed the opportunity to test its flagship, the Fet Valve CF hybrid preamplifier. Each circuit of our test unit features two 12AT7 tubes supplement...

Power-supply voltage is provided by full wave diode rectification of 230 VAC by a magnetic transformer. This design provides a quality audio amplifier. Valve amplifier circuit diagram. Valve (Vacuu...

This project uses a very interesting mode of operation of the vacuum tube, "starved cathode". Instead of running the tubes at a few hundred volts on ... of "natural tube distortion" and some overdr...

Andreas is one of the brightest new lights in the firmament of vacuum tube circuit design, and I was particularly impressed with his New Valve Order Audio SPA-II (Stereo Phono Amplifier-II) that co...

I am speaking more of audio vacuum tube amps than I am of microwave amps like magnetrons, klystrons, TWTs and the like. ... This is a serious design book with details on audio circuit design, equat...

The phonostage is the result of years of development and combines vacuum tube and solid state circuit topology to bring the beauty of valve sound with the long term stability that transistors affor...
