I'm not sure whether this section or the "High Voltage" section is the appropriate place for this, but here goes...

duncanamps.com is a terrific resource for simulation and modeling of various vacuum tubes, but one particular tube has eluded me for ages -- the venerable 3-500ZG. I'm currently using this tube in a high voltage current regulator (http://eskb.weebly.com/current-regulator.html) and would like to run simulations in LTSpice IV.

I took the generic triode models from duncanamps, but I couldn't figure out how to parameterize the generic model for the 3-500ZG. I got the inter-electrode capacitances and mu, but I'm not sure about all the the resistances and chi(X) parameters.

Does anyone know how I might do this?
