Does C3 have to be a electrolytic cap?

I also ASSUME the transistors in the circuit we have been looking at are concerned with voltage amplification. If we drive power transistors with a circuit the power transistors would be concerned with current amplification.

It's all current "amplification" amplification in quotes as you are not really amplifying anything
you are using a small current to control a larger current through the transistor

you are welcome
