I have spent some time this morning looking at a large number of Philco models in the 1940 RMS Yearbook, and I am convinced the reference to a "socket" terminal is a misprint.
In the majority of 1940 Philco models, the reference is made to connect an output meter to the plate and screen terminals of an output tube. Only in the instructions for the 40-180/185/190 and the 40-195/200/201 does it call for a "socket" terminal.
A socket terminal would not make any sense, because that could be any of the six terminals of the 41 socket. And you can't connect your output meter to just any terminal of the 41 socket and expect the output meter to work; it should be the plate and screen terminals.
You can also connect the output meter between the plates of the two output tubes. The instructions for the 40-205/216 call for it to be connected this way.
So connect your meter between the plate and screen of a 41 tube, and don't lose any more sleep over this.
