Don -

Neutralize right away.  It will not change with time or tube 
"life".

Best is to neutralize on 20M first, then go to 10M and 
"touch it up".   It's easy to go right past the correct 
setting on 10M, especially if you haven't done it before. 
The correct setting is a little "broader" on 20M.  Once done 
on 20M, it should only take a degree or two of rotation on 10M.

Did you verify the plate meter accuracy at idle?
