Bad capacitors in the B+ divider tree holding down the various voltages on the other side of the resistors? Insufficient drive from the deflection is going to get insufficient output from the horizontal tube, a lack of B+ from the divider will do just that. I don't think there's a free lunch with this one.
The only correct way to verify the HV is with a good probe, the big B&W sets had almost 20KV on the anodes but even with 10KV you should get some fuzzy light on the screen.
Personally I have a Mag T940 Astro Sonic combo, pics are posted here... somewhere.
