You're right, I screwed up on that post, my first post has the correct voltages I'm reading on V22 6K6.

Voltages at V22 are
Pin
3 = 80 (should be 160)
4 = 142 (should be 180)
5 = 0 (should be -18)
6 = 448 (no connection to the tube but Sams calls out the voltage anyway at 400v.)
8 = .6

Pins 3 and 4 start out high (200+ & 300+) but drop to the value listed as it warms up.
Pin 5 seems to be where the problem lies.

Re: resistance measurements on Horiz Osc coil, total resistance is 58 ohms with center tap at 15 ohms so the 20 is probably close enough.

Probably I should finish changing the paper caps, (quite a few left in areas outside of the Horizontal) and see what happens.

The vertical seems to be working though, the transformer rattles fairly loud when I mess with the Vert Height control
