After seeing the Win Analog preamp and power amplifiers at the California Audio Show a few weeks ago, I drove to the Win Analog offices in the San Francisco East Bay and interviewed the designer, Andy Ton. These amplifiers are very unusual, especially the power amplifiers, which use a single radio transmitter triode as the output tube in single-ended configuration, with an output of 100 watts rms in Pure Class A. Click on the photo to download the interview (it is a Windows Media Viewer file) to see why he used such a tube rather than a more conventional audio tube.
