It can be fixed ... Send it to John for a retransfer and we'll handle it. It's routine.

Most of the burbles start with an increase in pitch which indicates a slowing down during recording. My thought was an overly wide tape catching in the guides, but reel flanges or other annoyances could cause it.

Each warble starts with a sudden upward change in pitch, followed by a damped sinusoidal pitch oscillation with a period of about 40 milliseconds.  Immediately following the initial pitch change, there appears to be a slight loss of tape to head contact for about 10 milliseconds (there's a brief dropout which affects only frequencies above about 2 kHz).  Sure does look like the tape was jamming in the recorder.  If this was happening during playback, a) the initial pitch jump would be down, not up, and b) I think you'd see a very obvious mechanical disturbance of the tape break arm.
