[Amps] B- questions

[Roy]

About,

"...Isn't it also true that in a grid driven amplifier, the cathode is
connected to ground and the only B- connection to ground is through the
plate current meter.  This is done so the plate current meter isn't also
reading screen current. (etc.)"


So with a GG triode, a meter in the neg lead of the power supply filter caps 
to chassis ground, reads only plate current and not any grid current, right?
