Understanding DC Power Supplies by Barry Davis is a practical 1981 paperback that demystifies circuitry for hobbyists, students, and early-career technicians. 232 clearly written pages walk readers through real-world DC applications without heavy math overload.
The book is inscribed, not signed by the author, adding a personal touch for collectors of vintage electronics guides. Covers show light scuffing and both inner papers display foxing, yet the interior pages remain crisp, unmarked, and tightly bound—ready for bench reference.
Ideal for anyone restoring classic gear or teaching foundational electronics, this trade-sized handbook delivers enduring basics on power regulation and component selection. The smoke-free copy sits comfortably among amateur radio, model railroad, or DIY lab shelves.
Grab this affordable, gently-aged resource to power up your electronics library with reliable, evergreen know-how.
