A balun at the input of a tuner is looking at a reasonably low SWR. A balun
at the output is looking into the feedline which will typically be running
at a high SWR.
Baluns only work well when looking into a low SWR. They can experience very
high losses otherwise as well as failing to function as a balun.

In fact, the balanced tuner has a balun at it´s front end, looking towards
the transmitter. Other tuners have the balun at their backdoor, looking
towards the feedline.
What is now the advantage/disadvantage of which concept? Can anybody
explain that to me?
Yes, I am happy with my MFJ, but being an Elecraft-maniac in the meantime,
I would like to have the autotuner, which would need the extra balun.
Thanks to everybody undertaking the effort to answer me.
