*Thanks*
I was about to order some 1.5nF 2kV caps -- I'll try to find 3kV ones -- or go back to my fallback position of a 2.2nF 3kV cap.
It is interesting to see how the placement of these caps changes in various revisions of the boards. I also note that the 4 10k resistors I have are higher tolerance than yours but there seems to be no real purpose for this.
The yellow cap behind that is C6017 (2kV 1n5 5%) on my board, and C6005 is what we have identified as 3kV 1n5.
Yes, look like 125C rated. I have the choice between:
* Lower voltage (125C, 2kV, 1.5nF)
* Lower capacitance (125V, 3kV, 1nF)
* Lower temperature/higher capacitance (85C 3kV 2.2nF)
None make me happy.
