The Spring 1970 issue (Volume 1, Number 2) of The Audio Amateur continues to push the boundaries of home audio engineering with innovative speaker designs, investigative tours, and essential solid-state theory. Here are the highlights to entice your inner audio craftsman:
- L-C/H-Q, Mark I: Build a low-cost, high-quality bookshelf speaker that punches way above its weight. Utilizing an equalized elliptical transducer and a 10" baffle, this project delivers a level of clarity and realism usually reserved for much more expensive commercial designs.
- HEATH: King Kitmaker: Go behind the scenes at the world's most successful electronics kit empire. This exclusive tour of the Heath plant reveals the "tough-minded" engineering and scrupulous testing required to make complex audio gear buildable for everyone.
- Play them above the dust: Rescue your music from surface noise and static. Learn how a simple modification using "pips" to elevate your records can neutralize static charges and significantly reduce the rumble that masks fine musical detail.
- Price, Time & Value: Navigate the used audio market like a professional. This comprehensive study tracks eight years of price data for legendary brands like Marantz and McIntosh, showing you exactly where to find the best performance-to-price value in the second-hand market.
- A Bulk Tape Eraser: Achieve studio-quiet backgrounds on your magnetic recordings. Construct this powerful, inexpensive degausser from surplus TV chokes to completely wipe away cumulative tape hiss and "extraneous material".
- Learning to Use Transistors: Master the foundations of the solid-state revolution. This first installment introduces "Black Box" theory, providing the essential logic needed to understand how modern transistors actually amplify sound signals.
- Benchmarks: Elevate your workshop skills to a professional craft. This guide reviews the essential handbooks and manuals every serious audio amateur needs to build a world-class technical library.
