Default Rydel's triode model coefficients

Has anyone found a way of obtaining the 4 coefficients required by the Rydel model of the triode tube? I have tried various non linear regression tools, all of which failed. I wrote my own version of the LMA algorithm, attempting to deal with the discontinuity in the anode characteristic, but the result is unsatisfactory for practical data entry which is subject to random reading errors. I would welcome an opportunity to compare notes with a fellow enthusiast.
My current interest is the 6336A twin power triode.

Hi,

I used Mathcad to obtain the coefficients. It works pretty well.

<a href="Curve Captor | Free Science & Engineering software downloads at SourceForge.net" target="_blank">CurveCaptor</a> has builtin Rydel triode model among others, but why are you interested in the Rydel model in particular? Just curious...

Happy to know that curvecaptor has implemented my models ;-)
