The Vertical height problem was a drifted 680k resistor supplying B+ to the Vertical Oscillator, it had drifted somewhere around 2 meg, now the vertical has plenty of height.
This set has really strong audio!
Posted a short video of it running here:

The CRT is a NOS Rebuilt that I got off eBay, it had a short under the base cap, after removing the cap and straightening out the bent over wire it works great. Removing and replacing the base on a 7JP4 isn't a job I'd wish on anyone, nerve wracking to say the least.
The HV transformer is working great, it's been run a couple hours with no fade.
