Oh, I can make it pretty blatant and nasty-sounding too, if the
customer wants that. I've done that before too. Blues singer brings
in a record, says he wants to sound like that.... I set up 641 with a
teeny bit of underbias (using 1KC peak method), set operating levels
to the point where I get first audible distortion on a 1KC tone at -1dB
on the mark... voila! --scott


Above all noted..


Except that what I'm describing is seemingly a -lack- of distortion!.


Think the best it can do is about 1%.


At what level? Typical performance of a good recorder with good tape at 0 VU
is about 0.1% harmonic distortion, midband, almost entirely 3rd harmonic. At
higher levels, as previously noted, the HD stays low until you hit the point
where all of a sudden it takes off skyward, typically around +10 or +11 VU
for a tape where 0 VU = 320nW/meter..
