ok, i found the detailed wiring here on klov! I noticed that there are 12volt high and lows same with the -12. I read a old post about this and it was concluded a computer power supply would basically not work because of this. question. Mine is missing the blue capacitors on the bottom of the power supply but i'm getting all the main sounds minus the dog and hawk. What do the blue cap. do in this supply? Do they generate the hi, low? thanks for any input.
