Classic II C6 Cap: To where does the "+"-pad connect to?
Posted by: chrisrueckert on 2023-12-03 11:14:01
The + pad of the C6 capacitor came off. I checked the logic board schematics and noticed it would connect to a resistor. However, that resistor does not have a lable. Does anyone know where the pad would connect to?

Update: I found it. It’s R6 and the via connecting to it is just above the defective cap‘s pad.

I have a similar problem - I am dealing with 2 lifted pads on my Classic II board and haven't been able to really understand the diagram. Specifically missing a pad on C9 and C6. Based on this info I assume I connect to the via circled for C6.

But I am not sure about C9.
