I would match up the cap specs if I was going to borrow one, but I think that's going to be hit or miss, you might just be moving one problem from one cluster to another...Aw, i appreciate it, yeah a bit far away. Im confident I can do the soldering too I am wondering if I could just unsolder this capacitor from the spare mk3 cluster I have and solder it onto the b4 board. ANy idea which capacitor it could be on the mk3 cluster?
Honestly I would just buy some new caps and be done with it. They are readily available.
