Hello! I just purchased a used Commander II 2 meter amp and it runs high 
grid current all the time.  About 30 ma at 10 watts drive and 40 ma at 20 
watts drive.  I swapped the 3cx800 with a "good one" from a friend and it 
does the same thing.  Checked for shorts and ground connections in the final 
compartment but all OK.  Replaced the DC blocking doorknob cap and no 
change.  The link coupling is very rigid and I doubt it would change much 
from amp to amp or in transport.  Get about 450 watts out at 20 watts drive 
and 250 watts out for 10 w drive so think the tube is OK.  Help!
