I think you still have T2 connected backward. Emitter should go toward ground. As you know, the max per pin of the PIC is 25 mA, and T2 will have a significant base current as drawn. You may consider using a mosfet instead of the TIP41 for T2. If you do that, don't forget to put a small resistor in the gate circuit. There are lots of application sheets to show you how. I typically use something around 10 to 22 ohms, but larger ones can also work. They slow down the turn on of the mosfet, so don't go too big. John
