(These will not be electrolytic caps, but the smaller caps.) This can be a cause of interference.
If you use a scope to try and find this, it will have to be a good one to see the ringing, it will be a pretty high frequency.

I only did the electrolytic caps.
Do you have access to the Sams for the 25EC58 chassis? I think if you could point out where and LC or decoupling cap is in the horizontal circuit, that would help greatly. I think I understand the concept, but unsure when I look at the schematics. I see a 15ohm coil on the boost line and to a .47 cap to ground. Am I looking at the right stuff?
I'm still quite green with all of this, so hang in with me.
