OK, I just looked up Kevin's post

and see the note about a change effecting the noise blanker at S/N 824.  I'll bet 
a cup of coffee and donut that is when the 525 analog got the diode ring mixer.  
Note that the 525 continued shipping some time after that.  Just looked.  My 
latest 525 has S/N 1188 and my newest 525D has S/N 1810.  So the model 
number switch came somewhere in between.  I have successfully used the 
same noise blanker in both analog and digital Argosys.  Probably means that 
there is one version of blanker for 1496 mixer versions and another for the 
diode ring mixers.

Either the 525 with diode ring mixer or the 525D will turn in good performance.
