[Milsurplus] Leakage in Electrolytics

[Don Davis]

Jon Forster:

I wasn't addressing any comments to you.  I was addressing the comments of
James Duffer - as was very clear in my comments.  Besides, my comments are
exactly what you, also, answered.  No?

Your rash comments and use of capital letters indicate a possible adjustment
of your medications might be in order......
