Bad mica caps.

I have reservations about the reported mica cap failures. If they were stored in
the damp, and voltage applid before drying out, I can see a failure, but
otherwise it seems unlikely.
Here is what a friend said:

I think old gear needs to be dried thoroughly before applying power, especially
HV. If that were done, I suspect they would not have failed.
