Sure it is.  7.5mA is what's required on a pair, according to Johnson, 
and the book on the Ranger says -never- run the grid current on a single 
6146 in Class C higher than around 3mA.

BTW, Mark - I don't know if I ever thanked you for that plate switch for 
the Viking II.   I think I did tell you that I stumbled across one out 
there in the junk and slapped it in, and all was right with the world, 
again.  I've got this switch you sent in front of me, and I'm gonna 
-leave- it in the house (until I need it) so I know where the damn thing 
is!

I just hope I can -remember- where it's at, when I need to remember ~sigh~
