I have a OSA-5585 cesium PRS and it is not working.
On  the local manager i have a cesium module alarm. I opened it and found 
that the high power module that drives the cesium oven is not working  
it doesn't receive the correct voltages. Instead of 10 and 24  volts it 
gets 8 and 13 volts. So i pulled out the power board and  found out all the 
capacitors were bulged. I replaced all of them with the  corresponding 
and now i have 0 volts on its output and some smoke  coming from a diode on 

Does anyone have some schematics  for this unit, or could at least help me 
the connectors on the power  board? I found the output connectors that 
deliver the 10 and 24  volts but i don't know what the inputs are. If i can 
out what the  inputs are then i could debug the board easier.

Please excuse my  writing, english is not my native  language.
