Whilst this is a photo copy, and some of the pages are a little askew, it was all readable and intact. A real bonus finding an old manual for a classic piece of kit that no other site had.
Great stuff.

It was easy done, and I got exactly what I was looking for.

The manuel was exactly what I needed and I received it promptly. Thanks

Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.

HDA 200 Frequency Response Test Conditions � All measurements are done on a calibrated coupler B&K 4153 (artificial ear) with the standard cone YJ0304 above the adapter plate, type DB 0843.
� The pressure of the headband shall be 10N ± 1N. � The RMS input voltage to the headphone is 0.5 V. � The measurements are done with steady state sine
wave signals.
� The output impedance of the signal source shall be
<1 Ohm.
� Climatic conditions:
Temperature Humidity Atmospheric pressure T=20º C H=50%rel P=approx. 100kPa
All data are influenced by temperature, humidity and static pressure.
