Re: [ARSCLIST] manual pressure
Hello, Kevin,
As you are aware, harmonic distortion is essentially integral
multiples of the original frequency generated by nonlinearities in
the signal chain. Some is generated at the acoustic source.
If you can reproduce more of these highs, then you'll hear them.
I tangentially touch on that in my Azimuth paper on my website
http://richardhess.com/notes/2006/09/27/azimuth-hows-and-whys/
listen to the sample. You're doing the same thing but for spacing
loss rather than azimuth loss.
Lately I've been using a spare tape deck controller card in my A810
so as not to mess up the calibrated one and readjusting tensions
instead of using the thumb, but both work.
It is important to understand the cause of the spacing loss as you
may be masking a transport problem -- or it just may be a damaged
tape or a tape with poor slitting (i.e. damaged at birth).
Hope that helps.
Cheers,
Richard

Hello,
I sometimes apply manual pressure to old 1/4" tapes to increase tape
to head contact during low speed playback. I have found this
increases high frequency response. I have also found that it seems
to increase harmonic distortion. Is the increase in distortion
simply due to the additional high frequencies making it more
audible? Is this an acceptable practice?
