Question about using am 8YP4 test CRT

[Aperna1985]

Hey guys, so I'm home recovering from knee surgery and I'm finally getting to the point where I can move around, however I can't sit at my workbench. My wife is willing to bring my kcs96 chassis upstairs and put it on a desk for me so I can sit and work on it. Can I use my 8yp4 test CRT on it to make sure I got everything right when I'm done? I don't want to ask her to bring the whole cabinet upstairs that's a little much. I have never used one before so I don't really know what I need to do. The picture tube on the set is a 21AMP4A. Here's a link to the schematic. https://drive.google.com/file/d/1fKn...w?usp=drivesdk
