[Amps] Commander II output circuit

[R.Measures]

>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

•  30mA represents c. half of the rated grid dissipation.
