This is the formula for the one-stage PAE, but in my two-stage PA circuit, the drain voltages are different. I’m not sure how to adjust this formula.

I’m not sure how to adjust it when there are two Vdc conditions.
 

Use the definition of PAE and think of your PA as a black box and make your own formula.

PAE is the power delivered to the load minus the power delivered by the source over the total power consumed from the DC source.

So, measure: How much power is the RF source delivering? How much power are you delivering to the load? and how much power are you "sucking" from the DC supplies in total?
