You're only confusing yourself by changing the value of the resistor in the sim. When you monitor with the PIC, the resistor won't be changing. Current will be calculated with Ohm's Law using the value of the real, fixed-value resistor and the voltage across it. Those two parameters determine current. Forget the simulation. Forget the vacuum tube. Forget the B+ and the driver and everything else. The only thing you need to know is that current through the resistor equals the voltage across it divided by Ohms. Nothing else matters for purposes of monitoring with the PIC. Put that formula into the PIC along with the value of the actual resistor, and you're done.
