New Project RCA 16t152 Trying to learn to troubleshoot better

[Aperna1985]

I picked up a 16T152 for $25. I brought it up on a dim bulb and after playing with the high voltage tubes it came on. There was a little hum in the audio. I didn't have full horizontal or vertical deflection. The set will get a full recap, but like my last RCA I want to go section by section to try and learn from the failures. So first I want to repair it.the chassis is a KCS-47E. I figure let's go after the vertical first. It uses a 6SN7-GT for the vertical oscillator and sync amp. The output of pin 2 goes through the vertical oscillator transformer then comes out and goes to the height control. Coming off there are 2 caps that go to the grid of the vertical output tube. I'm guessing this is where I should start? Or should I be looking at the section of the tube that feeds the primary side of the oscillator transformer? This side effects the vertical hold control.

Also I attached a picture of what the picture looks like now. This is at line voltage, no bulb.

Here is a link to the schematic on the ETV museum website.
