Postby Absentee » Sat Apr 06, 2013 12:43 pm

Hey guys, built the a12 and during the final step of calibration when I tested with the opamp in and tested pins 4 and 6. Resistor 33 burnt out. I replaced it and now every time I power up with our without the opamp in it burns out the second it gets power. Any help would be appreciated.
