Thanks for the info and the patchsheets:)Although I figured  out D2 
for my self 10 mins after posting I used a 1n4000.I know all there is 
to know about diodes now:).I still can't get it to work. No power 
from the adaptor and the headphone jack doesnt work either. It still 
works fine with batteries;. Any suggestions?.
Damn wish I could find my multtimeter.
