The four transistors all measured good and I couldn't find any other faulty component. We don’t have any spare transistors of this type down here so there is not a lot I can do. Chris had a look and it had him buggered also. Eventually I ran out of time and had to put it aside for another day. I might try probing around and trying to find out where the oscillations are being generated from and try hanging a few decoupling capacitors around to see if I can improve or fix it. Tonight we had Mexican for dinner and latter on eight of us played this murder mystery game and I was the only one not to dress up as I was really tired and not really up for it but it turned out to be a fun night.

Does this look normal to you?
