CTC-10 issue

I have a recapped CTC-10 that looks really good. Makes a nice picture. However it has a waviness that seems to travel from bottom to top of picture with bottom and middle of picture pulling to the left and top to the right. Not very noticeable when showing a DVD movie or a picture from my agile modulator showing Verizon Fios, but I know it is there. However when hooking up a pattern generator or showing a cross hatch pattern via a DVD it is really noticeable. Almost like 60Hz getting through. It does it with all types of signal inputs. Set has all new filter caps and bypass caps. Any out of spec resistors have been replaced. All tubes are good.

I know bad filters letting 60Hz through can cause this condition. Can anything else cause this? Below pic showing DVD player menu shows the waviness.
