April 10, 200917 yr I accidentally ran into this while surfing websites for threaded rods to build my flexy: The H.P. Friedrichs (AC7ZL) Homepage Look at the photo galleries linked at the bottom of that site, some very interesting-looking material there (not necessarily hi-fi, but nonetheless intriguing!). I might look into this sometime in the near-future.
April 11, 200917 yr Author Been checking out the rest of his site. What a wealth of material there! No nonsense stuff. Very empirical methodology. Tried and true. I like this guy!
April 11, 200917 yr "Rooted in the same "build-it-from-scratch" philosophy that made his first book, The Voice of the Crystal, a success, Instruments of Amplification reduces complex devices to their essential elements and then shows how they can be constructed from commonly available materials" The Dark Crystal?
April 11, 200917 yr Author Like I said in that other site: The author states that some of his projects yield less-than-stellar results audio wise. Not being a DIY type of guy, I bought this paperback in hopes of learning how some things began. Not so much the "I'm going to make a kick-ass amp" as much as a "oh, so THAT's how it works!" I wonder if any of the "tech" he uses can be implemented into hi-fi gear, though. Well, maybe not the tech, but the visual aspect of his projects is definitely eye-catching. I think it's the steampunk kid in me who made me want to purchase this, because that's definitely what these amps remind me of... EDIT: To those of you who have speaker rigs, did you look at the rest of his site? Yesterday I saw a section on there about measuring acoustics in a room. here it is: http://www.hpfriedrichs.com/project-audio.htm
