All done and seems ok. Will need to have a few games tonight to test all clear. Once I noticed the numbers on the trannie things fell into place quickly as the schematics then made sense.  
Was good fun doing a bit of soldering, using the brain a little and the reward. Beats what I do day in day out at the moment.

Lamps look a bit brighter too, can this be the case or is it because I've had my head down close to a pcb all day?

More than likely.. brand new board so youll be getting the current you should have
