ATR-100 is down 3dB at 35 KHz, at 15 ips no less. Mind
you it drops like a rock after that, but it means flat
phase response out to 20 KHz. --scott

Just guessing but probably the only way to obtain that sort of response @ 35
KHz is to record the tone at -10 or -20 dB, rewind the tape, and adjust the
playback head while you measure the recorder's output. Good chance that the
played back tone will have a random bounce of serveral dB.

Nope. The needles are rock steady.

Will you get that sort of performance if you use yesterday's adjustment of
head azimuth? ;-)

Yes. That's the very, very cool thing about the machine. No more re-alignment
every morning. I check it weekly against the ref tape and do the record
alignment but I have not had to pull out the allen wrench since last July,
believe it or not.

If only the DAT and DTRS machines were so stable....
