Default Heater Power Supply Pspice model

I attempted to model a heater power supply circuit as described
by Morgan Jones [page 359 3rd ed] based on LM317 regulator.

With an output load resistance of less than about R200 the output voltage drops and oscillates.

Has anyone else had similar problems. I'm assumming it is a problem with the LM317 model [which is hard to find on the net] and does not really happen in reality.

Does anyone have a good model for the LM317.
