Do you heatsink the LM317T?
Yes, just out of practice. Too, everthing is mounted on and in an aluminum box.
I think there'd be too much too put inside a wall wart.
As for small amounts of small parts that were inquired about by another...
I've had great succes in ordering non-Shack stuff from All Electronics:

I have a mail order catalog of theirs, too. In it is listed a multi-volt/1-amp
wall wart, but it is a switching power supply, which would probably cause noise
on the bands.
