Because I like the occasional excitment I tried operating each set once I could see that there was nothing obvious as a safety hazard.
The Emerson had filaments light up, but nothing else. Surprisingly the ubiquitous 5U4 is not present in this set. LV rectification is done with a pair of 6AX4 tubes as normally found in damper service.
The Bendix on the other hand gave me a bit more of a show. I could hear the faint sing of the horizontal sweep, and--lo and behold--a horizontal line, classic of complete vertical sweep failure. Changing out the 6SN7 didn't make any difference, but it at least shows that the 12LP4 kine still has a little something left of it....
I'll get the vertical sweep going by hook or by crook, and if I get a good solid raster, and at least some noise on the screen indicating that the kine is responsive to signal, then I will go to the trouble of doing the recap work that will inevitably need to be done.
I snapped a pic of the display, brightness control set about midway and working fast so as not to damage the phosphor...
