Establishing the Basics: Foundations of audio circuit design. Audio Preamplifier Systems: Designing signal input stages. Audio Filter Circuits: Managing frequency response. Headphone Amplifiers: High-quality personal listening. Audio Power Amplifiers: High-power output stages. I have identified the book you are referring
Slone wrote the book in the early 2000s. Some transistors (like the 2SJ49/2SK134) are now obsolete. In the PDF appendix, he provides "substitution charts." Use the digital search feature to find all instances of "2SK1058" to see modern equivalents.
The Verdict Is The Audiophile’s Project Sourcebook PDF a replacement for modern Class-D modules and DSP? No. But if you want to build a power amplifier that will outlive you—one with massive toroidal transformers and discrete output stages that run hot enough to heat your listening room—this is your Rosetta Stone. Zoom into schematics without losing resolution
"The Audiophile’s Project Sourcebook" by G. Randy Slone is a highly regarded DIY guide that offers practical, engineered designs for high-end audio electronics, including amplifiers and preamps. While celebrated for its actionable, scientifically sound projects, the book is noted for containing some obsolete components and lacking coverage of modern digital audio technologies.
