Whelp... two steps forward, one step back.

I now no longer have a picture after changing 2 resistors. One of them was between phase detector and horizontal osc, and since I do still get a raster that's not the culprit.

The other one was B+ to the tuner, specced for 1.0K (R1 in the schematic), drifted up to 3 K and is in really poor shape.

I double checked that last one, and it is connected correctly. I'm also not getting any audio, just static so it's localized to before the audio gets tapped off... Haven't touched anything in that area though. Hope I haven't lost a tube, I will investigate more tomorrow.
