Default Pin-style headphones for S-38

They're right!!! I'm sitting here looking at a Trimm headset with the
frizzy wires and a big old Philmore phone plug... Actually, I have, in
the past, been able to "sort of" tin that type wire.. it burns off the
fabric content part. Only problem, its very delicate after all that. HI!!!

Many of the older 'phones use a cloth covered "Litz" type wire. This


stuff requires crimp connectors. Trying to convert from one type of
connector to another is a nightmare!


That's putting it mildly, never could get all those wires in that tip much
less get them to stay. RM~

It's called 'Tinselflex' in .UK, I think, and yes: it's loathesome stuff.

I think the original (pre-crimp) termination method was to bind it to
a piece of tinned copper wire for a length of about 3/4", form the
bound-in portion into a loop to fit the screw, then bind the free to
the main part to close the loop and apply an insulating and colour coded
whipping of silk thread to stop it coming undone.

I've been known to roll it in copper foil, ram that into a crimp tah
and then squeeze as hard as possible. It usually works unless you
need a very small tag....

Chris. (At some point I've got to do 4 ends the old-fashioned way, to
repair a WS-18 Morse Key - someone chopped the loops off because they
only needed the key jack and not the Tx/Rx connector. I'm not looking
forward to this.)
