I looked at GGG's  schems and I want to know if I can do this with the PS that I currently have (~14v rated 500mA)  ...


I went with the LM317 design because, at least according to RatShack online, RS does not stock the 7089.


I'm assuming that there would be no need to re-rectify the power so would I be ok with the schem I pieced together?


Thanks.

i just did the same as this on a 24v wall wart with a lm7824 and it killed a lot of the hum and it's pretty simple.
i think a lm7809 from futurlec is like 0.39$

  One of the best 'for use with effect' purchases I ever made was teh Spyder transformer..al all the tidbits [regulators etc.] to go with it.
  I used the 'dangling legs' wiring for the DC outputs.
