While we were preparing our list of specifications for our perfectionist's tape recorder discussed elsewhere in this issue, we suddenly came to a screeching halt at the spec which started "Scrape flutter less than . . ."
What, we wondered, was the scrape flutter percentage in a recorder in which scrape flutter is audible? Would it be 0.5%? Or 1%? Or even 5%? We perused the readily available literature, and were informed that "scrape flutter is caused by the tape's tendency to move past the heads in a series of tiny jerks in stead of in a smooth gliding motion." We were also told that scrape flutter is due to friction between the tape and the head surfaces, plus the slight elasticity of the tape that allows it to stretch slightly before being dragged along by another silly millimeter, and that it sounds like a rough edge riding on all signal frequencies between about 3kHz and 8kHz.
We received the following email this afternoon. Sad, sad news. I shall remember the Richard Beers of unlimited energy and enthusiasm, pictured above at the 2013 T.H.E. Show in Newport Beach, CA. Richard made audio shows fun for allexhibitors, press, and most all audiophiles of every persuasion. We’ll miss you, Richard.John Atkinson
Dear Industry Friends,
My name is Maurice Jung and I am the interim President for T.H.E. Show Newport. It is with heartfelt sorrow that I must inform you of the passing of Mr. Richard Beers. . .
AudioVision SF (1628 California Street, San Francisco, CA 94109) are having a free event Thursday March 17, 7:309:30pm, to preview Technics' new Audiophile 1200GAE 50th Anniversary Limited-Edition turntable and tonearm. This is not the Technics 1200 your local DJ played but a fully redesigned table with just about everything taken upstream except for the basic look!
Dr. Feickert Analogue's top-of-the line turntable, the Firebird ($12,500), is a generously sized record player designed to easily accommodate two 12" tonearms. Its three brushless, three-phase DC motors, arranged around the platter in an equilateral triangle, are connected to a proprietary controller in a phase-locked loop (PLL); according to the Firebird's designer, Dr. Christian Feickert, a reference signal from just one of the motors drives all threethus one motor is the master while the other two are slaves. (Man, today that is politically incorrect, however descriptively accurate.) Feickert says that the key to this drive system is the motor design, which was done in close consultation with its manufacturer, Pabst. The result is a feedback-based system in which the controller produces the very low jitter levels claimed by Feickert.
