[TenTec] Centurion Plate Current Meter

Mike - I fired up the Centurion -- The new plate meter is well damped --  
With a final plate current of 600 ma it goes up to 667 ma and drops back to 
600 ma - no undershoot with key up.

The grid / multimeter is not nearly as well damped -- With Ig set at 240 ma 
steady state , key down it goes to just about full scale 400 ma , down to 
160 ma , back to 280 ma , back down to about 180 ma  then two or three small 
swings to 240 ma . This  is how the old plate meter was . As a matter of 
fact I did not remember the new multimeter being that bad but maybe I just 
did not look at it that closely --  FWIW -- Hank K7HP
