Hi Eric,
Is there any special reason to use 2N2222 instead of ZTX450 (or other NPN) at the "Select" point in the circuits? I think I either got a bad batch of 2N2222's or they are more sensitive to heat when soldering and I'm frying them. Do you recommend using crocodile clip when soldering transistors?
