Been there, seen that.  An assembled album master may contain cuts that 
were recorded on different machines, and sometimes even in different 
studios.  This becomes really obvious when I'm doing Plangent 
transfers.  I can see when the bias frequency and flutter profile 
change, and I set azimuth on each cut by looking at the bias.  I have 
seen a master where the head tones were recorded on a different machine 
which didn't match *any* of the music.

When the album master is Dolby encoded, and several different machines 
were used for mixing, I can't believe that the Dolby setup on all of 
those different machines perfectly matches the head tones.  Fortunately 
the tape with the head tones recorded on a completely different machine 
wasn't Dolby.....
