Seems rather pointless. "Hey let's open a new topic for every question that's already been asked over and over again. This will give us lots of posts and topics and make this forum look big and really important!" Naaah. Which is totally the case here. Just not in a new thread per arguement. Btw, you didn't open any threads for discussions yet. You only opened "Where can I find..."-threads ;) About the PSU now: I swore I wouldn't help you because you were so lazy before but anyway..... To measure the 9VAC * make sure you set the multimeter to AC * check the 2 AC pins (not one AC pin and GND) * if that doesn't help you find out if there's 9VAC coming from the PSU then check every pair of pins (1+2, 1+3, 1+4, 1+5, 2+3, 2+4, ...) As long as you don't know if there's even any 9VAC coming from thwe PSU any further testing is rather pointless.
