[R-390] Cap leakage

[Bob Camp]

Hi

As far as I can see the metal jacket and the yellow jacket capacitors 
you see in the R390 are not in the same class as the "good old" black 
beauty capacitors. I have not seen a consistent problem with either 
one. The only thing I have ever seen a problem with are the black or 
brown body epoxy coated paper dielectric capacitors. The exception of 
course are those yellow jacketed capacitors that have been hit with a 
soldering iron. They don't survive that kind of treatment as well as 
the other parts ...

	Take Care!
