jtkmsms, there is some problem with your wiring and I havent' had a chance to go over it. The highest voltage should be at the cathode, pin 7, before resistor R100. Your readings show your getting higher voltage between R100 & R101 than at cathode? No can do. Voltage before resistor can't be lower than after, right! Go back and recheck your readings and are you measuring from B- (resistor R102, side that's not grounded? PL
