Output impedance

Hi,
What can I expect by putting 5.6K output trannys in a push-pull ultralinear system designed for 4.3K trannys?
I presume coupling cap sizes may need to be reevaluated.
Long story: I was going to build a new "Dynaco ST-70" based on a new driver and the Dynaco iron I had. After moving back to DC, I can no longer locate my project parts, so on an impulse, I bought a pair of Sophia Electric 5.6K p-p output trannys (who knows, probably from someone in this group). So now I may be potentially building a Dynaco amp with no Dynaco parts or topology.
Anyhow, I am hitting the books again, but am curious as to what issues I may encounter if I tried a direct drop-in of the Sophia parts to a design for a different hunk of iron.
