[Amps] 3CX800A7 low grid current version?

[Floyd Sense]

I see that RF Parts carries a "low grid current version" of the 3CX800A7 
tube, but haven't been able to locate any technical info on the tube.  I 
assume that this version of the tube might result in lower grid current 
than the standard version, at a given power level with all other things 
being equal.  Can someone verify that and are there any other 
considerations when using such tubes in my Alpha 89 amp?
