Topband: Balun for a balanced tuner

[Martin]

Topbanders, thanks so far for the replies. Some asked for more info on 
the tuner for clarification. Here they are:
Antenna to be matched:
2*41m Doppelzepp (is that a double bazooka for you english guys?) fed 
with abt 15m ladderline ( 12cm spacing, should result in 500-600 ohms).
Tuner: balun at input, 2* L (1 each side), 1 C switchable to either 
input (Cin) or output (Cout) of the Inductors.

                    +---------+--- L----+------
koax from TX---balun         C(in) or  C(out)   to ladderline
                    +---------+----L----+------
