Howdy, in ref to above,

A thot (or question) from the peanut gallery: I have read in several =
radio design books that it is not appropriate to use micas in DC =
blocking applications. I realize your use in the cathode ckt has pretty =
low DC across it, but never the less, apparently long-term DC causes =
some type of deterioration to happen to micas.

Comments anyone?
