[Milsurplus] "NOS" Caps: Don't Trust'em; Check'um!

[David Stinson]

You know, after 40 years of fixing this stuff, you'd think
a lesson or two would sink into my wooden head. 
But....

I'm resurrecting a pair of WWII Navy DAG portable
direction finders.  I needed to replace some .1 bypasses.
So I tacked-in some NOS caps I bought at our local
surplus outlet ( Knock Knock, David...First clue... 
why were they surplused in the first place, ya big dummy?).
And.... my screen voltages were still low.   Hmmmm.
So I wasted lots of time scratching my head 
over the diagram looking for possiblities.  
Long story short- one of the "new" caps 
was shorted.  Argh!

Moral:  Before you install it, check it!
