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.

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.
