U18 & U19 (LM339's) done as well. U19 previously socketed and changed (most likely due to batt damage) but checked under socket and buzzed out ok. Replaced LM339 and replaced U18 - socked and IC. That should complete it.
Jumpers existing repairs. All tested and working. The dodgy looking resistor also buzzed out OK. I don't like the colour of the solder on all the resisters touched by batt leakage, but I reckon the solder pads will be gone, so not worth re doing.
