Composite Vide on an Analog Oscope

Using the X, Y, and Z inputs, I was able to display composite video on a Tektronix 2225 analog oscilloscope. I used W2AEW’s schematic which can be found here: PDF. His related videos are here and here.

After three tries (and the release of some magic smoke) I was able to get this working and the video looks pretty damn good for a perf-board build connected to a thirty-year old oscope!
