Hi, I have a problem with a FTS-4040A standard, the LED major fault stays on forever. When I use the monitor program from Symmetricom I see that my OCXO stays cold and I have no Cesium oven voltage. The OCXO does feel warm so this one is warming up, I don't know if the cesium oven is warming up since I can't feel any heat from the CBT. I also don't see any current from the ION pump. After opening the unit I found a burnt resistor R1 on one board, I don't know what it's function is but I would like to know the value of this resistor so I can replace it. So here is my question: does anybody have any technical documentation for this unit and is it possible for someone to lookup this resistor in his standard so I know the value( pictures included for position). I think I have a power supply problem. I welcome all suggestions.
