WTB cassette deck with playback azimuth adjustment(CR7,DR1..

Archived from groups: rec.audio.pro (More info?)

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

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.

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.

There were several of them. Nak and Sony both made some. 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).

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.

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.
