I think it starts with 22 Corby will be able to tell you tomorrow. But do  
not forget even earlier models will benefit with a work around of A3. Its 
all in  the RVFR.

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!  :-)
