BC547/557 or 2N3904/3906 usually work as direct replacements.
For a hobbyist on a budget, this was the most valuable section. It included designs for: Signal generators (sine, square, and triangle waves). Transistor testers. Capacitance meters. Logic probes. 3. Power Supplies elektor 305 circuits
The Elektor 305 Circuits book is more than a relic; it’s an encyclopedia of electronic "building blocks." Whether you are a student looking to understand how a Schmitt trigger works or a seasoned pro looking for a quick solution to a power regulation problem, this volume deserves a spot on your workbench.
