Quoted from corsairflipper:A question, about oxide, its OK if I spray almost everything in the circuits and then obviously wait almost some hours to let dry, it will help maybe to fix some minor oxide contact problems? I go with a shower spray for first and see then what happen.
You'll cause more problems than solve that way. It's better/easier to trace out and track down the problem.
PBResource.com should have the schematics available to order. You can email them to ask. They ship internationally, but it might be expensive (as most international shipping tends to be).
