You just need a simple choke balun between the balanced ladder line and the
unbalanced tuner.
A choke balun can be made by winding a pair of wires (like 18 or 16 gauge
speaker cable) around a 2" diameter ferrite ring. 12 to 18 turns will do
provided cable length on the ring is not longer than 1/10th wavelength at
the highest frequency of use.
How it works is intuitively obvious.

Anyone feeding a dipole with ladder line feed from an Icom AH-4 ?
I can find articles from people using it with whips and random length
wires.... but I'd like to feed a dipole with ladder line from it.... one
leg
to the tuner's ground and the other leg the active tuner output. I think
I
would be able to float the tuner without a fixed "ground" connection then
.... the non active leg acts like a counterpoise in a balanced antenna
like
this right (?).
