Sorry, I'm rushing too much.
The coupling tube is the 1st RF.
I just repeated trials with antenna direct to 2nd RF grid, both with and without the 1st RF tube. The result for both was the same--what followed "Amazing," lots of reception with good volume control of all but the strongest stations.
The 1st RF transformer connections have tested correctly according to the (old) schematic, and the connections have not been changed from original, and are the same as on my junk Model 42. But I'll recheck them.
The 1st RF transformer connection to the 1st RF plate lead was "iffy." I had to do some pushing on the test probe to make the connection. So I resoldered that one.
And somehow I missed Old Coot's response yesterday. The filament lights and I get good Gm and emissions with my testers. Plus, I tried swapping tubes anyway. I also cleaned all contact surfaces of pins and socket and verified that they were connecting.
