Attempting first project - Some questions if I may

[albanks]

While I'm waiting for the parts and tools needed to fix up the '71 portable I decided to open up the '65 Zenith and get the chassis disconnected. I have 3 questions. Please see pics for reference.

1.) This is my first time dealing with the wafer board style capacitor. Can I still use the nichicon style capacitors? My procedure is to clip from the bottom, not re-stuff. I understand the negative grounding procedure is different.

2.) The HV anode connector thing is not sitting tight against the tube it looks like its missing a metal clip on the other side. Thoughts?

3.) I turned this thing on for 2 minutes, great CRT strength but picture was turned. I understand I need to rotate the yoke. When I opened it up what I was expecting to see was not there. Can you explain to me in laymans terms what I would be doing? There is a wingnut screw on top, am I in the right area?

Thanks in advance.
