Double up on PN2222A? #3

Closed dudesky71 closed 5 years ago

Why are these transistors in parallel? It would be more efficient and less wiring to use a higher current single transistor. A single TO-220 case 3 Amp BD241C from STMicroelectronics would work fine.

I used parallel PN2222 transistors because that was all I had and because this is a hobby project, it is more cost effective compared to high current transistors.
