You'll need a balun whether or not you use a balanced tuner.

That is unless you have a balanced transmitter.

.... or a link-coupled tuner, which works just fine without a balun
(or, looked at in another way, incorporates a balun as part of its
basic design).

You can save yourself the cost of a pair of ganged inductors by
inserting a choke balun between the balanced feedline and an ordinary
unbalanced tuner.

.... and being very careful to "float" the chassis of the tuner clear
of ground, and insulate it thoroughly.. If you don't do this, your
ground connection bypasses the choke balun, and/or you can be "bitten"
by the RF on the chassis which will often be at a substantial
potential above ground.
