I think you set the bar to high, because My Mechanics is the best restoration channel IMO, but here my list:

StezStixFix a very funny channel about fixing electronics, mostly SMD stuff over microscope: https://youtube.com/@StezStixFix

Baumgartner for fine art restoration: https://youtube.com/@BaumgartnerRestoration

Sebastian Lague for game development videos: https://youtube.com/@SebastianLague

Our Painted Lives for oil painting: https://youtube.com/@OurPaintedLives

I could keep the list forever (maybe I spend to much time in YouTube)
