I'm building a crown jewel, and I have one (maybe more that I haven't discovered) pair of pads that look to me that have bridged. I can run an exacto knife between but I thought someone might be able to give a good opinion before I move on too much further.

Touch each pad with your iron, heat will pull them away from each other. If they are too bridged, run your iron between there.

Those are probably two diodes that are supposed to be connected to each other end to end, which means the circuit board already made the connection and any solder bridging is irrelevant. I would definitely wait for someone else to confirm this (I'm running from one thing to the next at the moment), but you may be able to figure it out by looking closely at the instructions.

Even if it's not true in this case, it's something that's very common and worth looking out for. I've taken to testing spots like that with my multimeter to see that there is continuity before I start building, just so I know.

Yes, those circled joints are for a pair of clipping diodes that are already connected on the PCB, so a solder bridge there is of no concern.

There are several analogous pairs of adjacent joints on the CJ PCB because it contains multiple clipping diode arrays. You can determine these by comparing the labeled CJ PCB diagram HERE to the circuit schematic immediately below it. In this present case, you were inquiring about diodes D12 and D13.

Thanks for the replies everyone, I kept building and everything worked out!
