I posted a spreadsheet that will simulate a linear power supply with the worst-case load, with variable transformer ratings, reservoir capacitance, load resistance, rated output power, and basically everything else you need, which is attached to the post at:

It uses a numerical solution of the differential equations for the circuit. So no approximations are used.
A downloadable PDF file describing the spreadsheet, and the solution method, et al, is attached to the post at:

However, I recommend using LT-Spice, since it is much more flexible and powerful. It is a free download from linear.com.

If they don't offer samples, can you simply make some by bending the pins of a through-hole version into the correct positions? Or do you need some "real ones"?
