Where to get a diametric capacitating module for a PX5 Armada board?

I have a PX5 with the same problem. The original modules eventually fail and since they don't make them anymore, they're very hard to find. Someone told me that there is a way to modify the board to take a different part there but I'm not sure if that's true or not. The only way I know of to find a replacement is to find someone who will sell you their board and you can remove the module from it.
