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?


Both Radio Daze (www.radiodaze.com) and Antique Electronic Supply
(www.tubesandmore.com) list cotton-covered wire in their catalogs for radio
restoration.

As far as I can see, these web sites are offering cloth-covered stranded
wire, such as would be used for hook-ups under chassis and such. I'm
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.

I would draw a distinction between DCC, etc. and "fabric covered"
wire. I believe the DCC, etc. was just a simple wrap of fibers meant
to take up a minimum amount of space while still allowing close-wound
coil turns to be insulated from each other, while fabric covered wire
was covered with fibers which were actually woven together making it
much more durable. Fabric covered wire was more likely to be used as
hook-up wire, rather than coils.

Others on this list can probably pin this down better.

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".
