Jim Haggerman has a nice paper on the subject. In that he lists a procedure for measuring transformers to determine what values to use (its not a trivial test, but fortunately I had the right test equipment to do it). I ran this test on every transformer I had (about 25) and found out that even though the resonant frequency for these transformers varied all over the place the RC necessary to damp them wound up being remarkably similar. These values were sort of an average over the transformers I had. I then tried that combination on all of them and found that it worked fine for them all. So this has become my standardized value for all transformers. So far I have not found a transformer where this does not work.
