Pin 2 on U7100 is 0.449 with C7105 and 0.445 without. Thanks, I'm using 330pf for c7116 till my extra donors arrive. R7105 is reading 23 ohms when it is a 10 ohm resistor and was reading 10 ohms when I installed it which is weird. If it was blown you would expect it to go a lot higher than just double it's value? Pin 3 on U7100 is now reading dead short, 0.00 diode mode and 1 ohm resistance to ground. I got two ISLs with my last order, not sure if I should try the second one or not since the first one seemed dodgy this one probably is as well.
