Part 1: What Are the "304 Circuits"? A Historical Overview
Between 1980 and 1989, Elektor published a series of themed compendiums. The most famous were the "304 Circuits" books (often mislabeled as "300 Circuits" due to rounding). These were not magazines but thick, softcover books compiling the best projects from several years of monthly issues.
The series included:
- 304 Test & Measurement Circuits
- 304 Digital & Computer Circuits
- 304 Audio & Hi-Fi Circuits
- 304 Power Supply & Battery Circuits
- 304 RF & Communication Circuits
Each book contained exactly 304 verified circuit diagrams—everything from simple LED flashers to complex frequency counters and early microcontroller programmers.
How to Safely and Legally Obtain the PDF Repack
Here is the caveat. Elektor International Media still holds copyright on these circuits. The company actively sells reprints and digital archives (e.g., the "Elektor 30 Years of Electronics" DVD-ROM).
Therefore, the "repack" exists in a grey area.
2. The 70W MOSFET Power Amplifier
Before Class-D dominated, Elektor published a rugged 70W RMS amplifier using HEXFETs. The design includes full protection (DC offset and overcurrent), making it a favorite for DIY hi-fi restorers.
