Hey, thanks for the reply...

I did it all so carefully and all the joints look good, but I might try and re
do some of them. Isnt it a bit strange that it happened after i plugged in a 9v
power suppply instead of a 7.5?

Also the fact that I have straight wired 2 randomish! Points to make it come
back to life feels like it m,ight have something to do with when I plug in the
jack lead it turns the powr off with the mains!?
