As far as I can see, these web sites are offering cloth-covered stranded

looking for "D.C.C." wire such as was used for winding coils. I guess it
would be considered "magnet wire" ?

"Magnet wire" is not fabric-insulated. Instead, it has a coating of
varnish, formvar, etc. It will work well for winding coils, but it
won't look like DCC.

I believe DCC is actually what was used in the early days for what we
today call "magnet wire." I'm not old enough to be sure of this, but
my impression is that varnished magnet wire replaced SCC, DCC, SSC &
DSC at some point. No doubt this conversion took place over some
period of time.

You're right, Jim, my phrasing was poor. What I was trying to convey is
that if you go to a store or catalog today and ask for "magnet wire",
what you get will be enamaled/varnished/formvared wire - which is easily
available. So if you are looking for cotton-coverd wire, don't ask for
magnet wire.

And a note OT, I set up a new computer a few days ago. In the process,
I managed to send out just TWO newsgroup messages with my real address
in the header before I remembered to munge it. One of them was the
message above. Damn, those spambots are good! My spam intake
immediately jumped about 10X. My SWEN-related quota jumped from 2 a day
to about 50 a day. No choice now but to simply wait for it die out.

But to those who say that the spambots are smart enough to detect and
correct a simple NOPSAM in the address, I say "not so".

Double Cotton-Covered ("D.C.C.") Do they still make this stuff? I would
like to obtain some for winding RF coils for homebrew radio receivers.
Anybody know of a supplier or maybe have some on hand?

(I missed the original post.) I think you could get it from either
New England Wire or Kerrigan-Lewis, if you were willing to order a
minimum quantity. The "cotton" will be Dacron or something though.

Otherwise I would look on antique radio websites or find some defunct
equipment to disassemble.

Well, heck, if somebody wants DCC that bad, an old RFC (R F Choke)
is one "source." That old favorite of many moons ago, a 2.5 mHy RFC
was once an all-purpose thing, usually with 4 "pies" of windings and
lots of turns of small diameter wire that had either CC or DCC
insulation.*

I just don't know WHY anyone has to restore some old thingy to the
exact appearance it was supposed to have. Electrons won't care.
If the appearance is very important, just get a bunch of the wire in a
loose wrapping between two fat dowels and spray-paint the wire with
white primer. Primer has the dull surface, doesn't look shiny and
"false." shrug

* A 2.5 mHy inductance and 1000 pFd capacitor resonate very close
to 100 KHz and some way back in prehistory of the late 1940s used
that resonant circuit to make a "calibrator" spritzing harmonics way
up to 29.7 MHz. I did that as a beginner in 1947...then learned more
and got a Bliley 100 KHz crystal for "accuracy." Crude, yes, but a
lot more accurate than those wide-band tuning dials with separate,
uncalibrated "bandspreading" second tuning. Pfui.
