Well, someone suggested that I should run a cooling fan for the trans and the outputs. So, I did it with sucess and here is how it went.
Parts:
- 2= Radio shack 1 9/16" fans (300mA total draw)
- 1= Bridge rectifier, 1500mA (1.5 amps)
- 1= Filter cap, 1000uf, 35V
- .5 amp fuse
- heat shrink tubing, 1/8" diameter
- soldering iron and solder
The PS trans had a 8V AC terminal. I used that terminal to feed one side of the rectifier and gounded the other end of the AC input. Hooked the positive of the fans to the + terminal of the rectifier and hooked the negative of the fans end to the - terminal (and grounded them also). The filter cap goes to the + as well and the - grounds. The fuse goes inbetween the rectifier and the AC volt tap.
This is what I came up with. I made 2 metal brackets to hold the bottom fan under the PS trans. Its is my hope that it will blow air down beside the windings and the iron core, around and down the other side. The output tube fan is mounted on the shield.
These fans are small, so they dont blow alot of air. But they do move air around so there is no hot spots under the covers.
