Thanks for the info John and all.  I'm certain that many on the TMC list
(including me) have been looking for the correct plug with not much success.

If all else fails, it may be a simple matter to replace the original with a
Cinch-Jones 2 pin socket and plug, as they are still readily available.  I
have not checked the size relationship, but they look close. The bad news is
that any change to such a classic TMC receiver may not be acceptable to
owners.

Folks,

Ironically, the data for these connectors can be found in the TMC drawings
stash, whose keeper I became about a decade ago, thanks almost entirely to
Bruce!.. :)

The female connector on the GPR-90 is J-4, and the parts list for the
GPR-90 indicates that it is TMC part (and drawing) number JJ-146.  The
drawing, which has been scanned, shows this part to be a Cinch 16034.  It
has a 1/8" and a 5/32" pin, allowing the connector to be polarized.  Turns
out the mating connector is PL-123 (this drawing has also been scanned, but
is upside-down.. sigh), a Cinch 2724, or possibly 11631.  See

https://tmchistory.org/tmc_drawings/drawings_db/pl/pl_100_199/pl-123.pdf

So, now for the fun part:  finding a Cinch 2724 or 11631.  Maybe the usual
places..?  Ebay, Fair Radio, SS of Nebraska...?  It's also possible that I
have one in my stash.. I'll check over the next day or so and get back to
you, Bruce!
