Great work, Clark. Not sure what to make of the copper shielded electrolytic. Maybe because the old ones didn't have the neg lead tied to an outer metal can. But I don't recall seeing that practiced on any other ratio detector circuit. Possibly Andrea was just being very picky with their design, trying to keep hum out of the audio. Although it seems copper would be more of an RF shield than magnetic.
