The German company selling components for the Z-Match is actually one of the
ham radio magazines here. They sell lots of kits and components, including
Ten-Tec kits. The company's name is "FUNK AMATEUR" (www.funkamateur.de ).
If I recall correctly, their components are specifically for the
"single-coil" version of the Z-Match, which is described on Lloyd Butler"s
site (VK5BR: http://www4.tpgi.com.au/ldbutler/ ).
The UK commercial Z-Match was the 2-coil version.
Unfortunately Mr. Annecke passed away about 6 or 7 years ago and no one took
over his business. His components and tools to build them were sold to a
company in Holland but I have never seen anything emerge out of that.
Thanks on the tip about components from Palstar.

Ok, I understand what you meant. The cebik article I
posted has a link at the very end to Butler's site.
Who helped develope the original "Z" match in New
Zealand. That's good reading too, on Z matches. Lots
of technical graphs on matching efficiency, etc. Was
the german company you refered to about selling parts,
Annecke? Palstar Tuner company sell all their high
quality components off the shelf for the homebuilder,
in case anyone's interested. Check out the pictures on
their website, nice stuff! I built the circuit in
William Orr's "Radio Hanbook" 23rd Edition. Work's
great and I built it with a lot heftier components.
