Step into the world of professional-grade audio engineering and vintage restoration with Volume 8, Number 1 of Glass Audio (1996). This issue features innovative DIY projects, deep technical analysis, and essential guides for the tube enthusiast:
- The Country Boy's Capacitor Microphone – Stop paying thousands of dollars for studio microphones. Veteran designer David Royer shows you how to build a high-quality capacitor microphone for about $100. Using the Primo CM 23B capsule, this project delivers results that rival "uptown" professional gear, making it perfect for both recording and speaker/room evaluation.
- Driving the 300B – Tired of "slogging, closed-in" sound from your 300B-based amplifier? Concert piano technician Reid Welch shares his journey in tuning the ultimate driver setup. By moving from traditional RC coupling to interstage transformers, he reveals how to achieve a riveting, textured sound that finally lets your triodes sing.
- Distortion in Tubes, Part 2 – Master the technical nuances of small-signal triodes with Rickard Berglund’s continued measurement study. This installment focuses on cascode circuits, providing critical data on gain, output impedance, and distortion for common tubes like the ECC88 and 12AT7 to help you select the perfect tube for your specific design.
- The Amplifier Distortion Story, Part 2 – Dive deep into the physics of audio with the second part of Norman Crowhurst’s landmark series. Learn how to identify and measure elusive low-frequency transient distortions and discover the design strategies needed to prevent feedback-induced overload in high-performance amplifiers.
- Collecting Glass—an Overview – Navigate the competitive world of the vintage audio market with expert Charles Ochs. Whether you are a "purist" looking for the perfect brand-name tube or an audiophile seeking the ultimate sound, this guide offers essential advice on treasure hunting in junk piles and the ethics of restoring classic "hollow-state" hardware.
- Product Review: The BK Power Amps – Join George Brooke as he puts high-efficiency power amplifiers from BK Electronics to the ultimate test. Comparing them against high-end Accuphase gear and driving legendary speakers like Klipschorns, this review determines if these modern designs provide an outstanding basis for a genuine hi-fi system.
