Here's a video of where we're at now. I replaced a 10M and a 100K resistor that were about 30% high. Pulled in the picture somewhat better:

Still as you can tell, it's got slightly insufficient height. I had to adjust the linearity to compensate for it to get (close to) a full raster. The 6SL7 tests like new. I figure this is some type of low emission in the vertical output circuit, and the only component I can think of in there that I haven't changed or tested is a 100 PF cap.

Or am I being too picky?
