I'm thinking some of that W.S. grass of the right color and one of those anti-static applicators might be the solution there.

Hmm...model railroading...cause AND cure for hair loss?
Thanks to this thread, our local club now has a nice new (old) power supply to power structure lights on the layout. Many thanks, Johnny_reb!

The Radio Shack 5 1/4 inch floppy disks were 168KB, not 140MB.

My thoughts on power.
As I began reading an article on how to convert a computer power supply into a cheap or even free bench power for electronics a thought began to creep into my mind. You see I have always been a tinker of sorts, I love to challenge of taking something and making it into something else entirely or taking something broken and fixing it.

I know that there are a few that can see where I am leading. If something brakes you try and fix it before you take it to someone else. You hate to throw anything away, you hate to pay good money for something you yourself can repair. I myself grow up working or playing with every piece of junk or some gismo I had found.

edit: after locating the about wires cut them from the 20 pin connecter.

You do not have to open the case!You do not have to do this mod!You do not have to use this information!
It is up to you, do as you will.
Now a sub- note;
If you plan to always have a load on the unit the load bulb could be omitted. In short if you will always have your layout lights hooked up or another load hooked up to the unit I see no need for the the load bulb itself. But it is a good indicator that the unit itself is up and running.
