Scarred cap
« on: April 01, 2018, 01:52:13 PM »
Any idea what causes this? It's a cap on a power supply board. While it looks like it could make contact with the aluminum fin, it's just an illusion. There's no way it could have bent over that far.

I don't know what caused it, but I know I would replace it.   My WAG is a manufacturing defect that didn't reveal itself until power or enough heat caused it to act up.

The JD9 that cap is in has an audible hiss in it. Tried multiple different remedies - tubes, OP amps, rerouting wires, etc and so far nothing has tamed it. So I was in there looking real close and found that cap. Some suggest multiple caps and diodes be replaced in the power supply, I'll add that one to the list.
