I don’t think you need spares of anything…
I burn things out occasionally due to a disregard of hardware that I have from my other projects:
If I make a mistake, it’s just a 20 cent regulator. If you don’t have spares or play with hardware much you tend to treat the devices with a bit more care.
In any case, I’ll try to put together a video on replacing SMT stuff. I have some cheap audio amps on the way for a radio I’m building and I’ll use that replacement to build a video.
