Replacing the capacitors on the Wells 4900 was fairly easy, and actually kinda fun. It was my first experience soldering on a board, but I managed to complete the capping without issue, thanks in no small part to a couple instructional videos on Youtube. Thank you, Internet, I really do love you.

These boards can take some abuse. Check out this creative bit of repair by a previous owner:

I covered that exposed bit of wire near the top with electrical tape and let it be. Everything works fine for now, but I’m waiting for it to explode violently or something. Some day I’ll replace it just for the peace of mind.
