It is shown that in the large level k limit the perturbed WZNW system with negative k arrives at the WZNW model with positive k.5 pages, LaTex file, QMW-93-25. (The value of the second conformal point of the perturbed WZNW model is presented. Please note that a title is changed.)High Energy Physics - Theorytext
