My name is David van Harn, and I have been an audio enthusiast since my high school days in Chicago's SW side in the late 1950's. Built a 80Kv/500KHz tesla coil using 811A triode tubes in 1958 and conducted experiments in "high frequency phenomena" which earned me a 2nd place in physics at the Chicago city-wide science fair in 1960 - the pinnacle of my "scientific career." Poor color vision ruled out a career in clectronics, so I ended up getting a degree in Conservation of Natural Resources from UC Berkeley at the age of 36. Then I worked in sales and design of solar heating systems, and later, sold aerospace precision rotating components and finally, sold and did tech support for PC-based scientific software. Became an IT specialist, and finished as a contract senior network administrator plus desktop support for San Francisco corporations, including being on the Y2K team for the Pacific [Stock] Exchange admin section. I am currently starting a book on my audio history and the "psychology of audiophilia."
