This URL worked last week. In fact I was watching video from the channel and left the window open over the weekend. https://www.youtube.com/watch?v=uEIRXYQO4_Y

It played for 10 seconds until buffer ran out and it said video not available.

I can still google the name of the account X Electronix Master Club and the link to it is the first link but it goes 404.

Its just a hobbyist electronics channel that I just found last week. It had 18K subscribers and many old videos that are now just gone.

Strange!
