In Reply to: Linear / Switching / Regulated / Unregulated PSU's? posted by Traffo on August 2, 2005 at 12:14:13:
Let me suggest the following approach:take a look at this:
Http://www.jameco.com
search for the following part numbers--
205911cj
252856cj
174844cjThese are examples of regulated AC-to-DC tabletop or wall transformers. This has the advantage isolasting the PS from the XO board. However since you probably need split rails (+12V-0V--12V) you use a 24V PS. Then use the simple circuit shown in the following link to spit into +/-12V.

You cac "air wire" this or use a small piece or Vero (proto) board at the power input socket. Just be sure to chose a transformer that has a bit more current capability than you actually need.
