I'm inclined to agree - it wouldn't be the first instance of a cracked hammer by any means, and pre-recorded tapes which are completely free from audible speed variations are much less the exception than they should be. Simply looking at the tach head output won't tell you a lot - if the system is running closed loop abd fluttering, the tach head output will perforce flutter too.
