The new part arrived (the extra can is from my TV).
The RCA part number is 100430 and the Meissner part number is 17-6014. I got this from
Play Things of Past. I also checked with
Moyer; they don't have the Meissner part but they do have a Miller 6025, which is equivalent according to their records.
I'm leaving tomorrow morning for another short trip, so I probably won't have time to play with this until next week.
Perhaps breadboarding this circuit is not a bad idea. In different schematics, the value of L42 is given as either 11 or 12 muh, and the value of C209 is given as 4, 4.7, or 6.8 pf. I believe I have all the needed parts on hand, except for a ready-made power supply. Maybe I can pull out the power/audio chassis from my Admiral 24C15 B/W set and tap that for B+ and filament voltage.
