Transformer information.
Sometime back
in 2001, my good friend from the
Recordist list, Chris Preston, and I began our Sunday Afternoon
telephone
conferences, and very early on, a favorite topic was
transformers.
For one silly moment, we thought we could actually fabricate our own
iron!
Chris had experience winding guitar pickups, and I held Hope Eternal
that
about anything could be built in "the garage" (and VLSI chips could be
built in the bathtub <g>).
In the course of my web searches, I
ran across
some interesting companies and materials suppliers. I whined and
pleaded a few times on the various Recordist lists, and gained some
extra
insight (Tom Bethel supplied a few useful links which are incorporated
here). All that being said, I'm still a LONG way from rolling my
own....iron!
The Usual (and some
unusual)
Suspects, offering Finished Goods:
Jensen.
Probably the most famous brand in the US. Plenty of info,
schematics,
and price lists.
Sowter.
Good Jensen alternative from the UK for many apps, including "vintage"
restorations/clones.
Lundahl.
Quality Swedish iron, including tooob amp transformers.
One-Electron.
Speaking of toobz, Recordist list contributor John Atwood offers nice
SE
iron and other related parts. He also has founded the "Tech's
Filing
Cabinet", a great collection of Linkage.
Plitron.
Toroids R Us from Canada.
Hammond.
Also from Canada, iron, enclosures, and other goodies.
Carnhill.
UK manufacturer of some Neve iron. USA
contact is Vintech.
Stevens-Billington.
Another apparent Neve UK supplier. One other Neve supplier who's
name escapes me has "Radar" in their name. Anyone remember??

trade
groups:

many useful links and papers.

not transformers, but guitar pickup winding is an allied art!

surmise.
