Fw: [R-390] Some thoughts on capacitor leakage

[ToddRoberts2001@aol.com]

I have found leaky silver-mica capacitors inside various RF Deck transformers 
over the years also. They caused the sensitivity to go down on certain RF 
bands. Other people have determined that over the years  the silver tends to 
"migrate" across the mica insulation causing the older style moulded 
silver-mica caps to become leaky and intermittent over the years. Good idea 
to stock up on various sizes of new manufacture epoxy-coated 500V silver 
micas to keep on hand for future repairs. Mouser Electronics has a good 
selection.
