Hello, I have two questions about this circuit.
1- What is the efficiency of the circuit and how to find it?
2- What is the purpose of connecting two transistors in parallel?

Thank you for your time.

  1. If you can compute the power in which will be small given the wasted power in R1, and you can measure or compute the output power which should be even smaller given that the circuit basically has no power to speak of because of R1, then yes.
  2. Beats the hell out of me
