Right tool, right job

You can make almost anything work. Getting things to work right is a bigger challenge.

Take for example a Power Plant AC regenerator. We’d love to use Class D amplifier technology for the output but have consistently stayed with good old Class A/B. Right tool, right job.

Class D amplifiers can be terrific for the reproduction of music and so too can Class A/B. The reason either can work for music but only one for a regenerator is because the jobs are different: powering loudspeakers isn’t as extreme as powering equipment.

Speakers might demand instantaneous current approaching 10 amps for short periods of time—a workable challenge for both amp topologies. Equipment and AC power routinely demand 50 to 60 amps for a regenerator—at 5 times the voltage presented to a speaker. That’s a job for an amplifier without a heavy output filter.

In the same vein, using a vacuum tube for the input rather than the output, or a DC servo instead of a blocking capacitor, is the essence of using the right tool for the right job.

Hard to know what’s right and what’s wrong if you’re not a designer yourself. Which is why it’s important to find a company or a designer you can trust.

Right tool, right job offers the best performance.

A quiet revolution

My father Don was one of the few in our neighborhood that had an actual sound system. It was a cobbled together group of separates: Rek-O-Kut turntable, Stromberg Carlson electronics, homemade speakers. The few neighbors that had sound systems relied upon the classic all-in-one console, while everyone else got music through a simple radio.

All that changed in the late 1960s with a quiet revolution. Japanese receivers, speakers, and turntables began infiltrating American homes—not through stereo stores at first, but through the military. It was the height of the war in Vietnam, NATO troop buildups in Europe, and cleanup activities in Korea. The US military was everywhere and so too were the audio stores and PX where low cost Japanese (and eventually American) hifi equipment found their way home to America. Entire systems could be had for hundreds of dollars and GIs in search of bargains, their pockets filled with cash, flooded the stereo outlets.

By the mid 1970s, when the Baby Boomers were taking over, the stereo situation had completely changed. Now, there were almost no homes, dorms, apartments, or condos without the minimum requirements of a turntable, receiver, and pair of speakers. It was the heyday of the music revolution.

When I think back on these days it occurs to me there was a perfect storm of simultaneous revolution going on: the British music invasion, Woodstock, vinyl LPs, FM stereo radio, folk music, protest music, Motown, and what today we refer to as Classic Rock.

Without many taking notice we went from radios and the occasional console stereo to a near complete penetration of sound systems in every home—and it wasn’t just America. All over the world people plugged in, played music, and changed the world.
