Thanks MM,
Page 2. Its U16 I'm looking at (LM339). U16 & U17 control the direct switches.
I found one track which was done, that I've repaired. But its hard to work out what goes where.
IF we can work out that pins 1 to 14 are suppose to go, I can buzz each one out. I think there is one which still is broken that I need to find.
