I've had nothing but trouble with the two 419As I bought several years
ago. I'm guessing that the caps are simply under-rated for dissipation,
because it's common for them to fail with only 100W at 2:1 or lower VSWR.
My experience has been that they won't handle more than the 30-50W it
takes to drive my Titan amps. At that level, they seem to hold up OK.
They're currently sitting in my storeroom, having been replaced by a
pair of W3NQNs that are on long term loan.
If you're going to replace any of these caps, I'd try to find some with
higher dissipation ratings.
