Hello,
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 
out  
that the high power module that drives the cesium oven is not working  
because 
it doesn't receive the correct voltages. Instead of 10 and 24  volts it 
only 
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 
values 
and now i have 0 volts on its output and some smoke  coming from a diode on 
the 
board.

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

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