Sheesh, and we still have boxes of the things brand new at

I would test them before use. These are mostly stacks of
mica dielectric and aluminum foil electrodes rather than
plated "silver mica" types. Mostly, they were use for high
voltage transmitter circuits. They do not have the stability
and very low leakage of the plated type but were useful for
HV bypass use. I think they may suffer from the same
problems with degradation of the bakelite shell that other
caps seem to have. Also, the fact is that most of these caps
are getting to be very old.
