OK U20 is out and socketed. I'm happy with the socket and solder. I'm still very much a novice in this area but I do enjoy it. In the top r/h/s you can see some of the batt damage around the resistor's. This is what concerns me. I've scrubbed and scrubbed with tooth brush and don't think it will get much cleaner. I know any PCB under macro 5 megapixel shots will look not good, but hmm.....
