I'm planning on using a pass transistor and heatsinking both devices.  I ordered a couple of heatsinks but on the advice 
of another list member, am looking for something more substantial and think I've found it.

That seems to be what's going on here.  I put my money into the transformer, rectifiers, and filter caps.  I just wanted 
to make sure that if I didn't go with the solid tantalum, the regulator would still perform properly (e.g. not break into 
oscillation, etc.).

Sorry for the OT bandwidth guys.  I need to shut up and just build the stinkin' thing...

Thanks again,
