E<I>ditor's Note: There is a large contingent of </I>Stereophile<I> readers who design and build their own equipment&mdash;the DIY (do it yourself) crowd. Herv&#233; Del&#233;traz from Switzerland has been e-mailing us photos and stories over the last year about his own ambitious DIY amplifier design, so we asked him if he'd be willing to share a chronicle of his progress, starting from the beginning. This is the first in a six-part series written by Mr. Del&#233;traz.</I>
