WTB cassette deck with playback azimuth adjustment(CR7,DR1,dragon,etc.)
I am looking for a cassette deck that enables manual azimuth
adjustment for playback.Would consider a deck that does not record,if playback is flawless. Thanks,Raanan |

Take the loading door cover off Get a $6 set of mini screwdrivers Go to it. Works well enough for the occasional job, but if you're doing this on a daily basis the screw wears out. It's possible to retrofit a vernier control on (I have done it to the Tascam 122), but these days it's probably cheaper just to buy a used Dragon. --scott -- "C'est un Nagra.

I thought at one time there was a deck that AUTOMATICALLY adjusted the playback azmuth itself. Was this true? If so.... How well did it work? I asumme it did some phase comparison between the L and R. Mark |

Mark;

I asumme it did some phase comparison between the L and R. Mark The Nakamichi Dragon does this. It divides one track (not sure if it is the left or right track) into an upper and lower half so it can compare the phase response of a MONO signal and adjust the azimuth for optimum phase alignment of the upper and lower windings of that track. The azimuth adjustment is motorized. Any tape made on any machine could have the azimuth optimized by this approach. John Hardy The John Hardy Co. www.johnhardyco.com |

Also, there were a bunch of cart machines that did the same thing (cart machine azimuth stability being even worse than that of cassettes, if such a thing can be imagined). If so.... How well did it work? I asumme it did some phase comparison between the L and R. Right, and for the most part it didn't work too badly, at least the Nak ones didn't. They could take a minute or so to settle down, but once they did, they worked pretty well. I'd rather have a manual vernier control, but then I like driving a car with a manual transmission too. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Take the loading door cover off Get a $6 set of mini screwdrivers Go to it. I did that once many years ago when I was a college student. I was poor, so I had my Sony Walkman plugged into my NAD receiver's tape inputs. That Walkman had a little plastic piece that could be popped out which left a hole where you could easily adjust the azimuth. Cassette sound sucked, so I regularly adjusted the azimuth for whatever I was playing. One day I stuck my little mini screwdriver in there and started adjusting like normal. Soon I smelled a funny smell of smoke and iron, and I noticed the treble response had gotten much *worse*, not better. Eventually I noticed the lack of treble wasn't just with tapes but was with CDs and radio too. Then I realized the funny smell was both my tweeters saying "goodbye, cruel world". I still do not understand how it happened. I didn't have the volume up high at all. It was quite some time ago, but I vaguely remember that some kind of buzz or high-pitched noise would happen when I inserted the screwdriver. The noise didn't seem particularly loud, so I was never concerned about it. I'd be interested to hear if someone can explain exactly what might've happened. Perhaps the screwdriver triggered some kind of oscillation for some reason, but I don't get why it would. (But then, I don't purport to understand analog electronics on anything but the most basic level.) - Logan |

The Nakamichi Dragon does this. It divides one track (not sure if it is
the left or right track)... It's the left, as the left is closer to the edge of the tape, and thus more subject to skew and other azimut errors. |

The noise didn't seem particularly loud, so I was never concerned about it. It was ultrasonic stuff, which is why you couldn't have heard it. And knowing the stability of some of the Walkman clones back then, the screwdriver may have had nothing to do with it. But if you were hearing a high-pitched squeal, that's not a good sign. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
