Ed, nice pix, thanks.
Looking at the Elko Varicon I have in hand (DXX455-1000-3) the contacts are
essentially hermaphroditic. This chassis mount housing gives up its contacts
fairly easily, just unbend a tab to release. Turn them 90 degrees and you have
something that works like the mating PCB side contact. Only part requiring
effort would be to trim / mount / hold them in line somehow.
I'd offer up mine (no big deal, I have more) but I suspect it's the smaller
contact - dual row 0.1" centers vertical, 0.2" centers horizontal, rows offset
0.1". If you think it might be workable let me know.
Thanks for the offer, but yes, those are the mini contacts. I've got a
few of them and they just don't fit. I actually scored a box of the
right connectors on the auction site a few weeks ago. I've thought
about how to turn and support the contacts. I doubt that I'll go that
route because if I have to I can salvage spare contacts from the
existing boards. Each board has 16 contacts, but they don't use them
all. But I'd hate to do that.

Third, I'd like to build an extender board, but I can't find the connectors.
The contacts are called Varicon and are used both on circuit boards and in
connectors. The connector version is available, but I can't find the board
version. The last picture in the above gallery shows a close-up of the
connectors. They were available in regular and mini versions. I need the
regular ones that stand about 4.3 mm high. The minis are about 3.5 mm high and
won't mate with the regular ones. New ones could be loose or spaced out on a
plastic strip to make installation easier.
