shunt regulator using VR tubes (with ccs like g pimm) and circuit load

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

for example: I have set the CCS to output 60mA. But when I measure the load being used by the circuit, it is only 50mA.
questions:
1. What happens to the extra 10mA? Does it pass through the VR tubes going to ground?
2. would the result be the same if the VR tube has been replace by some other shunting tube regulator like those found in various places/guides such as sbench and tubecad?
thank you for the help.
