Ok, hows about another fun question? I've got some possible coupling caps
evidently made by the Dearborn company (if Faradnet is correct) for the
millitary, i believe. I identified them by the "620P" identifier, which i
thought was a sprague-only thing. They look like "Vitamin Q" types. Anyhow,
has anyone knowingly had any audio-related experience with capacitors of
this dielectric? I'd like to hear of your impressions.

Have fun,
Nick
