Mr Fix
I did the measurements, not sure if they were done properly.

I do not get a dead short between Pins 2 and 3. I get a reading of .2 ohms. That reading is on both 42 output tubes.

Between Pin 2’s of the 2 42 output tubes I get no reading at all. 0.0

The readings I took from the red circled #42 output tube Pin 2 to the lugs of the output transformer were - 0.0 to #1, 0.0 to #2, 0.3 to #3 and 0.0 to #4. 
The readings I took from the green circled #42 output tube Pin 2 to the lugs of the output transformer were - 1.4 K to #1, 249 ohms to #2, 0.0 to #3 and .2 to #4.

Between Pin 4 of the 42 output tubes I get 291 ohms and 154 ohms on the center tap. That center tap I used is the one shown in the blue circle.

Between Pin 5 and chassis ground on both 42 output tubes I get a dead short.

I’m not sure if any of my readings were done correctly. That’s why I’m including the pics to show where I took the readings from. The “interstage” transformer confused me. I hope this helps. The radio works but obviously there are some issues.
