[Milsurplus] BC-669 connector

[Jim Whartenby]

RobertHow much effort do you think would be required to open up those three #16 contacts in a 28-8P connector to accept #12 contacts using a tapered Swiss file?  A half day's work versus patiently waiting for a couple of years seems worthwhile, doesn't it?Regards,Jim

Here is Robert Down's response to me back in 2012:
________________________________

Sorry, but the connectors are NOT AN 3108-28-8S or P.  They are actually AN
3108-28-767S or P.  Which were custom modified from the 28-8.  That's why
they are so difficult to find.  Amphenol does not appear to have actually
made any -28-767 inserts.  To add to the confusion, most if not all of the
modified inserts that I have seen still have -8 molded into the face.  The -767
was only marked on the barrel (and not on all of them, either).  The
difference is that the 28-8 has 10 #16 and 2 #12 contacts.  The 28-767
has 5 #12.
three of the holes for the #16 (A,B,C) were bored out for #12.


I think Bill Perry has been sold out of the proper connector for at
least 15 years. I finally did find an original cable just by patiently
watching ebay. It took a couple years and shipping from Italy, but I
got it.
Good Searching,
