This issue features four major DIY projects and expert reviews that bridge the gap between classic tube warmth and modern engineering: SPICE and the Art of Preamplifier Design, Part 1 – Norman Koren demystifies the design process using highly accurate computer modeling. Using the legendary Dynaco PAS as a platform, he demonstrates how to use the free PSpice program to achieve nearly perfect frequency response while eliminating the "grittiness" caused by RF interference. High-Performance Tubed DAC Output Stage, Part 1 – Jukka Tolonen tackles the "last solid-state fortress" in the signal chain: the CD player. Learn how computer simulations can help you design a tube stage that matches the technical performance of modern semiconductors, ensuring your digital audio finally "glows in the dark". An MC/MM Preamplifier – High-end designer Erno Borbely delivers a hybrid masterpiece that offers the best of both worlds. By pairing low-noise JFETs with tubes capable of handling large signals, this design achieves professional-grade noise performance and massive overload capability for both moving-coil and moving-magnet cartridges. Big Mother Power Supply – Millard Johnson introduces an over-engineered, "cost-no-object" power supply designed to be the heavy-duty heart of any amplifier. Featuring massive computer-grade filter capacitors and regulated outputs for screen grids, this unit is a tube builder's dream that provides a substantial upgrade to imaging and sound quality. Book Review: Inside Tube Amps – Eric Barbour reviews Dan Torres' accessible guide for musicians and novices. Learn how to troubleshoot, repair, and modify classic Fender and Marshall circuits with this clear, non-technical manual for the hands-on enthusiast. Product Review: Radiotron Designer's Handbook on CD-ROM – David O'Rourke explores the digital reincarnation of the "holy bible" of audio design. Discover how this 1,498-page resource has been transformed with interactive hyper-links, making half a century of essential technical data accessible for the modern designer.
