The FTC Proposes Eliminating Its "Amplifier Rule"

When I joined Hi-Fi News in the mid-1970s, one of that magazine's stable mates reviewed cars. An automotive writer appeared in the pub one lunchtime—"I rolled another one," he said, as he joined us at the bar. It turned out that one of his tasks was to take a car he was testing to the skid pad to see how many lateral G's the car could handle. Of course, the chances of a consumer turning that car over were minimal, but the reviewer was investigating the edges of the performance envelope.

As I became familiar with audio measurements, it struck me that the equivalent of the skid pan test was the thermal preconditioning we perform when we get an amplifier on the test bench. Even if an end-user doesn't drive his amplifier into thermal meltdown, the edges of the envelope need to be explored.

Tim de Paravicini, RIP

Dammit! Tim de Paravicini, the Baron as he was known, passed from this mortal coil on December 17th, 2020. I loved the guy. His deep, steeped, sharp-elbowed engineering bona fides in matters of electronics, cars, planes, and life earned him plaudits from all over the world. [Editor's Note: this appreciation of Tim's life and work now includes personal memories from John Atkinson]
