This is still in the 1251 Counterpoise kit. It was available separately ~1
yr ago as a separate part/kit, though not on the list then. Old P/N 80402.
Value is .5-24 uH. These were also used in the 291 and other '100W' tuners.
A very simple, decent affair, large toroid in a pair of molded shells that
set the form for the inductor turns. The tap is a 'w' shaped fingerstock
that moves over the turns, staying in contact at all times. My '291 has held
up very well in portable use; just don't throw any amount of power at it
until the match is getting close.
I work here without an amp and am looking to upgrade my Dentron Super for
the home station. The Measures design is the direction I'm headed, when I
can get the time. These guys looked like a good alternative to
Cardwell/Johnsons' 229-203 at $60 and up per copy.

list, which suggests that it may be discontinued.
