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.
