Some time agor I wrote regarding our similar problems with lag times on 
our Techne thermocycler.  (Not to mention the breakdown of three blocks within 
a 1 year period.)  This problem cannot be changed in anyway I am aware of, 
except by changing instruments.  PCR failures due to lag times cannot be 
differentiated from inconsistent well-to-well temperature variability, or lack 
of template, etc.
