You can measure the line current (from the tube into the tank or out
of the tank into the load) using a current transformer, such as made
by Pearson. You would find them used on EBAY maybe or in some
scientific lab junk. This may work up to 10 MHz or so, depending on
the frequency. If you have a good high frequency voltage divider, you
can determine the voltage at a node, and from that calculate what
current must be causing it. If you mean the circulating (reactive)
current, this can be calculated from the Q, just do the circuit
analysis on paper and draw the loops of current and corresponding
voltage drops, you should be able to come up with that current.
