    With some of the frequencies mentioned; I'm wondering whether that's the root of the problem.

    Using a 1 nanofarad capacitor yielded lower current than when I used a 100 picofarad capacitor. 120 ma as opposed to 150.

    Do you think that the breadboard is creating too much resistance and is increasing the resistance for Rsc?

    my breadboard was creating too much resistance. I'm transferring the circuit to another one.

    Did you see the size of his inductor? How big is yours and what is the value of its inductance?

    Note that at your relatively small currents the solderless breadboard should work just fine if it has not been abused by installing parts with leads that are too big.
