I've counted them, and if I could get hold of Count Von Count, I'm sure he would agree - the LC 475 has eleven little capacitors (ah ah ah! thunderclap!)...

As of 2026, they're all leaking. And unless your board somehow won the capacitor lottery during manufacturing, your logic board is no different.

My small stack of LC 475 logic boards is down to one that need to be recapped. Let's tackle recapping this last one tonight, and see if I can get the Dealer Upgrade LC 475 chiming again! Or at the very least, get a feel for which of the three boards is repairable, and which may be suitable parts donors.

Will there be any bad traces? Will I melt plastic? Will the board work once I am done? You'll have to watch to find out!
