went ahead an replaced the .035, and the remaining .1 in the grid of the output triode of the 6GF7. changed the lineairity (more range now) but still have the line pairing going on. only thing left is the 50uf cathode bypass.

I am going to reset up the lineairity, then do the purity and convergence.

Its close just not perfect, like my CTC-16 in the stockholm. I will try a few more 6GF7's including the one in the stockholm just to be sure its not a tube issue.

I would really like to get these two side by side and scope the vert circuits, esp for horz noise, but they are both quite large.
