        08/11/2015 Rich Abbott Modification Description
            Dylan modified this chassis to have a different filter capacitor on the monitors of each quadrant drive.  The capacitor (C32 on D15000016) was 1uF and is now 0.01uF.  The effect of this is to change the measured transfer function in the test report from -44dB/-152deg to -16dB/-78deg at 1kHz.  These units still have C36 = 1uF in each quadrant drive.
