Hi Jeffrey,
I followed the component locations (grid refs) that was not the issue, the issue is my paxolin strip board seems to vary from the schematic. I've taken a photo of it and its orientated as per the schematic diagram. the components don't follow exactly
for example at the bottom R64 next up should be C111, its not there!
likewise C79 not there just a gap, unless they are hidden under, in which case this is going to be tricky and loads of potential to make mistakes as I will have to unsolder 12+ connections

P.s. An indirect benefit in helping me is you've started on one of those 62's which have been calling you for some love and attention.
