Hello,
sorry for a question not directly confocal related.  We have a Zeiss Axioplan 2ie, about 7 years old.  Its power supply failed last night with an outpouring of smoke.  The most obvious damage is a 400V 150 uF capacitor that shows white powdery substance on its top (can't tell if this is ash or corrosion), signs of overheating and loss of oil.  

Has anyone else experienced power supply failures with this model?  

this scope is used about 1,000 hours/yr.  It is switched on with the first user of the day and switched off by the last user.  

Thanks,
Glen
