Hello Folks,
I think I need to clarify something I saw on this forum. It could be my mistake when I replied to one of my customers about tube life of 5977. It is 5000 hrs. not 3000 hrs. Please look at this link where it is showing tube specs. The life is 5000hrs at 30 degrees Celsius ambient temperature. Here is the link:
