Most amplifiers meter plate current in the negative plate supply lead which
is at or near ground for safety. Strictly speaking, cathode current is the
sum of plate and grid currents (plus screen current in a tetrode).

Hi Dave:
Few amps use a plate current meter. The reason is safety. The meter face
is the only thing that protects the operator. Safer in the cathode.
