Delinquent electro

**Hi to all,

just pulled a 470uF, 35V pigtail electro form an old piece of German made
audio gear ( Dynacord ).

Behaved initially like it was very leaky, pulling a 16 volt DC rail down to
just 2.6 volts.

Tested on a bench supply, with variable current limiting, it behaved exactly
like a 2.7 volt zener.

Tested on my trusty Bob parker ESR meter - it read open ( ie more than 100
ohms).

Blasted with 2 amps of DC current - it instantly ceased being a zener and
the ESR dropped to around 20 milliohms.

Repeating the above treatments induces event more schizoid behaviours.

This Kraut made cap is plain bonkers .....



..... Phil
