One of the chillest retro hardware repair channels, love watching it.

I especially enjoy Adrian's methodical approach to identifying the root cause of a problem. That way you can learn a lot about how these things really work and fail, and not just watch somebody quickly identify a faulty chip and replace it.

I've learned a lot from Adrian's videos. He shows all the mistakes he makes as well. One good thing is that he no longer shows the cleaning and retro-brighting stages... because wow, we've all seen that a thousand times now!
