I am in a journey to repair my TEK 475 Analog Oscilloscope that I had purchased at a local Craigslist seller. It has been a couple of iterations and have still been unable to narrow down on the exact problem. This page will attempt to journal the steps, pictures, troubleshooting, etc. Once I figure out the issue and the solution, I will try to encapsulate all of the key steps taken to a resolution.
Here are a few pictures and YouTube video collateral.
