What does some reglar programming look like on it at this point?
Oh, regular programming looks ghastly, with wrong colors and rolling bars, not to mention lousy focus. Here is the witch reaching for Dorothy's ruby slippers:



After I finish the resistor hunt, I will do some more voltage checks and look at the color AFC alignment procedure and other adjustments.

By the way, here are the outputs from T115, the quadrature transformer. First is terminal D, which goes to the G-Y demodulator grid. Nice and regular:



Here's the output at terminal F, which goes to the 6AL5 phase detector (V120) and to the R-Y demodulator grid. Similar amplitude, but not the same pretty sine wave:
