If you are going with the 10W resistor you may have a hum problem unless you increase the value of the filter caps (not the input cap). A choke will work much better. Value isn't very critical 5-10H @ 75-100ma would work ok. If you have an old power transformer or a big output transformer you can use that for a choke too.

figure out what all those squiggly meant.
