The biggest issues I have with gear maintenance are more around desoldering and not scorching boards.

I can DIY projects without issue, but measuring in situ requires a bit more research and trying to carefully remove large components without lifting pads is tough! I tried to “upgrade” a cheaper compressor once and had to remove the caps and whooooo what a mess.

I’ve got a decent iron, know how to use flux and solder to pre-prime the original to wick out, but there’s so much practice I need before I trust myself for good component swaps.
