[TMC] SBE Mic connector?

[John Poulton]

Richard, Eugene, and the group,

Here's where the 'Drawings' page at tmchistory.org can be somewhat helpful;
you just have to do a bit of detective work.  And, please feel free to bug
me if a drawing  you need hasn't been scanned.. I'll do my best to get it
onto the list!

First, referring to the parts list for the SBE-2/-3 list in the SBE manual,
you'll find that connector J101 has TMC part number JJ-133-3.  Part numbers
are also the drawing numbers!  That particular drawing has been scanned,
and there's a note on the drawing that says this connector (the panel
connector on the SBE) is an Amphenol 91PC3F.

Doing a bit more digging in the later SBE manual, you'll find that it
mentions the male mic connector that mates with 91PC3F as TMC part number
PL-132-3.  Once again, referring to this drawing (though it hasn't been
scanned) the note on the listing says that this is an Amphenol 91MC3M.

Needless to say, these Amphenol parts haven't been made for a long time,
but I found a bunch of them listed on ebay (at fabulous prices, of
course).  See, for example:

https://www.ebay.com/itm/3-Pin-AMPHENOL-91MC3M-male-microphone-connector-cable-plug-Vintage-NOS-USA-QTY/163525717988?epid=1301663412&hash=item2612e46fe4:g:D14AAOSwmqZcWKCT

So, you wanted a rare and obsolete part, and you wanted it *cheap*?!  You
ask for too much, grasshopper!
