Vintage test equipment
One side of PS Audio most of our community never gets to see is our test equipment. We share with you the products that came from using test equipment, but rarely the actual pieces that perform the measurements that make our products possible.
Today, all our test equipment is fancy-schmancy ultra-expensive Audio Precision gear. These are state-of-the-art computer-controlled pieces that are truly marvels of engineering and represent the industry standard.
But they are hardly the kinds of equipment we started with—the kinds of equipment that bring fond memories to my heart. For many years as Stan and I (and later) me and our chief engineer, Bob Stadtherr, designed PS Audio's products, we used older purely analog test equipment, like the pictured Hewlett Packard 334 distortion analyzer.
What was great about this gear was its hands-on feel. You felt as one with the equipment, watching the big meter drop lower and lower (if your circuit was performing as you hoped) as distortion levels dropped below audibility.
I miss those days of hands on equipment, of through hole parts I could actually see and feel (as opposed to today's tiny surface mount parts) and, perhaps more importantly, read the values of.
