The bias voltage is used in other places on the rig besides just the 
finals.  That said, have a look at the "drake mods" article written by 
VE3EFJ  http://www.dproducts.be/drake_museum/Drakemods.htm  select the PDF 
version and look for bias. The 5 or so hit will be the CW discussion.

He discusses backing down the bias provided that you are only running CW. 
Keep in mind that the 6JB6s are a small linear amp, and adjusting then out 
of linear will effect you CW note.  Might get the FCC looking your way, or 
at least a few fellow ham unhappy with your key clicks.
