Update
Have ordered the parts from RTBB and also managed to get some of the smaller pins and connectors from Jaycar along with desoldering braid and desoldering suction, so will start rebuilding in the next few days. I have also ordered a crimper so will try and do the job without soldering. Looking forward to getting this machine running smoothly. Great challenge - would have no chance of success if it had not been for the kind assistance of everyone here.
