Grr - still no vertical! After a bunch of troubleshooting I discovered adjusting the vertical linearity brought the vert oscillator to life.
Unfortunately horizontal hold is non-existant.
A bunch more troubleshooting lad me to a mistake in one of my new couplates. Luckily, a little jumper wire took care of that!
Finally I could assess the picture tube properly. It takes a while to warm up, not that bright and a little bury but is watchable in dim lighting.
Linearity and centering are pretty good.
