Rick, I'm sorry to say that unit is not a link coupled
tuner. It is a tuner, like most, with a 4:1 Balun on
the output of the tuner, so it can be marketed as a
balanced line tuner. If your interested in building a
true link coupled tuner, there is a great deal of info
on this page. http://www.cebik.com/link/link.html .
Also a neat echnique to make your own inductors, for
any power rationg you might want. The second link is a
parts source with the Caldwell Condensers. Caldwell
bought out the old E.F. Johnson and Hammarlund
Capacitor plants. So the parts are available new if
you absolutely can't find one at a flea mart.
http://www.cardwellcondenser.com I've bought four of
these variables, in like new condition for a total of
120 dollars. Just snap them up whenever you see them
on the want adds. Also, the Cebik article on balance
tuner designs gives the circuits and construction
plans for Link-coupled tuners.
