On a related note does any one know the likely serial number ranges of the HP5065's that would benefit from this treatment ?   (Or is there any other easy way to tell the units appart ?)
Thanks to all concerned for the effort put forwards on this project.    It may sway me towards actually buying an HP5065 at some point in the future.   The efforts are appreciated.

Another factor that limits the (apparent) interest is that the 5065B is 
one of the most expensive and hardest to find Rb standards around.  Even 
on the used market the price for a 5065B in good condition can be 
breathtaking.  If Corby's work can be extended to other, more common 
units, the level of interest will explode.  The question, of course, is 
whether the more common units will see any improvement.  Since not all 
5065B units show the same improvement, I won't be holding my breath!  :-)
