Richard -

The Dragon is great, but I actually prefer the Nakamichi CR-7A for its
manual only azimuth adjustment. I think that once you get the playback
azimuth in the optimum position (as indicated by a vectorscope or whatever),
a CEDAR AZ-1 or equivalent can track small deviations better and faster.

I have a Dragon also, but the manual states on p.9 "The NAAC operates with
musical signals above 3kHz recorded on the tape. If a tape with music
containing only little energy in this range is used, the direction indicator
may sometimes flash and the adjustment will require more time..."

This is often the case with oral histories in my experience.

Our Dragon needs service (!), so I really haven't done an actual shootout
with the CR-7A, but I feel very comfortable using the CR-7A/CEDAR combo at
this time.

For an audio cassette player in current production, take a look at the JBR
Standard Cassette Playback/Transcriber Unit at

http://www.jbrtech.com/prod_stand.html

This is a special purpose unit and it's a bit pricey - being designed in
part for high end forensic work. With multiple narrow tracks the need for
accurate azimuth correction is reduced. The drawback is lower s/n ratio.
Perhaps after our building program is complete we'll acquire one.

The Tascam is a studio workhorse.

If anyone wishes to resurrect a Nakamichi cassette player, here is Nakamichi
America's recommendation as of 6.4.02:

ESL will custom modify CR-7As to add varispeed. This is important because
cassette decks are notorious for running at different speeds.

Hope this helps.

Later. Parker
