Hi Folks

I have done something similar to what is being discussed.
I started with a pair of kits from ECROS Technology 
instead of starting from scratch. I wanted a very simple
and easy to assemble low cost  PS for one of my Atlas/J/O
setups. I was using two Bench supplies and I need them for
other toys.  The two models I started with were the 
Mini-PSU model. A simple Series regulator fed from a 
wall warthog transformer. 
The info on them is available at this link http://www.ecrostech.com/General/MiniPsu/index.htm
I paid about  $15 for them if I remember correctly.
In light of the discussions on this reflector I am researching some suitable simple Crowbar circuits 
to add additional protection in case of a power surge.  I currently run them on a small 
AC Line UPS / Conditioner unit from Office Depot.
For the Negative supply I use a surplus wall PS with a simple zener regulator ckt.
Looking forward to the discussions this evening on Team speak.
