Lookin' good. At this point you could get rid of the Bulb, and start putting all the tubes back in except the horz output, watching the B+ reading as you add tubes.
As more and more tubes pull current and load the power supply, the B+ should come down and the negative supply rail should come up (though it probably won't show the full -100V yet).
Finally if all's well at full line voltage, add the H output tube, being ready to shut the set off quickly if needed. Hold an insulated screwdriver next to the 1B3's plate connector and see if you can draw an arc. It should draw a healthy 'air arc' of a quarter inch or more, proving the H output and fly are running. If no arc, shut 'er down.
