Basically, the video shows you how to properly set up your Technics 1200 turntables, including leveling, grounding, platter assembly, attaching a cartridge or headshell, and balancing the tone-arm. The Technics 1200 is the industry standard deck, but people using any other turntable brands will gain a fair amount of knowledge from the video too.
In addition to the video, I also have a page on my website that talks about this turntable in a lot of detail:

I know that the old series turned out to be useful for thousands of people, so hopefully this single version is a bit more convenient. If you have any questions, feel free to post them in the comments section on YouTube and I'll try to respond as quickly as possible. As always, if you find this video (or the turntable page on the website) to be useful, I appreciate you posting links on your blogs or favorite message boards.
