REPLY:
The rule is simple:
To avoid having the B- meter read grid current, connect the grid current meter
from ground to the side of the B- meter which goes to the cathode. If you
connect it to the other side of the B- meter, the B- meter will read the sum of
grid AND plate current, which you do not want.
