Sorry for the hiatus, work has been insane

Yes jumpers are in place

First post here so bear with me. And I should correct myself the tweeters are working they are just not getting a signal. I purchased four RF-3II speakers. Two sets of consecutive serial numbers. The person told me he had owned him since new never had an issue. However, when I got them home and unloaded them, I’ve heard something rattling in one of the speakers something loose inside. I proceeded to remove the tweeter, because I could see that there was none present when I looked in the horn and found that the coil was melted on one of the speakers. So, without even doing any investigation, I ordered a new diaphragm, put it in and still nothing on further investigation. Neither of the one set of speakers had tweeters that were working. Obviously the one has been repaired so my question is what would be next to troubleshoot the issue? Assuming it’s crossover issue because all the connections are good. What could I test next to find the faulty component? Or are there upgrades I should do to the crossovers while I’m in there? Any advice would be greatly appreciated

Please excuse my ignorance in advance, but I have a RW 12 that wouldn’t power on so I remove this played amp and started looking and noticed that the board that is numbered 660038RA was leaning up against the component next to it which I believe is the transformer? I will show pictures of both can you tell me what damage that could’ve done to not only the board but maybe the other components as well but I’d be safe and changing out that board and where might I get it? Thank you in advance for your help. .
