Power Amplifier Design using MRF136
I found that the figure 1 in MRF136's datasheet provides us with the
  150MHz test circuit, but with no accurate Capacitor or Inductor
  Values.




Unless I'm missing something, all the capacitor values seem to be stated below the picture.


  L1 -- 2Turns, 0.29" ID, #18 AWG, 0.10" LONG


This will be an air-cored inductor and there are several calculators on-line for getting the inductance value. For instance this calculator tells me that the inductance of L1 is 0.03649 uH: -



Note that the coil diameter should take into account the wire gauge hence the figure it needs is internal diameter plus one wire thickness. I didn't do that in the picture above.

THIS calculator also comes up with the same value.
