Good news, :).
I found last issue with sound. It was a pig to find. I had to check each individual component and check each one was going to the correct places.
Tur ns out the feedback resistor wasn\'t connecting the output of 2nd op/amp to input of 2nd op/amp.
Sound is now absolutely perfect, :). I will send some pics.
Also I have managed to repair tracks without having unsightly wires showing, :). I have tried to keep it as tidy as possible.
I will now move on to the last caps to be replaced. Both are by the clock, which doesn\'t look to good either, the simm sockets for the last simm are corroded quite bad.
Dont worry though, we are almost there, :).
I also tested your clock and that holds time perfectly with battery attached. This board just amazes me, lol. I still cant believe it was working to the extent it was, :).
I believe the first four pics below are of the repair work to the tracks & components around the OP/AMP section....

Yes all caps will be replaced. Still changing them. Just changed he last 47mf caps, 2 just fell off with out effort taking the track with them, :(.
All sorted though, ;). The simm socket is perfect. I have cleaned the area where leakage was. All working fine.
Just testing it some more before changing last caps on main board, then I will sort the CPU card.
