Leaking Coupling Cap?

[Jamier]

When I installed the upgrade board I also installed V-Cap ODAM 2.2uF/630VDC caps in the coupling cap position. Everything sounds great, but this morning I found some drops of oil under the preamp. When I turned the chassis over I found oil on one end of the A cap. What are the chances? I have never had an oil cap leak so, I am wondering how long before this thing fails and will it be catastrophic when it does?

I would just let Chris know. While this is exceptionally rare for a new production cap, it is definitely not out of the realm of possibilities, and Chris will definitely stand behind his products.

Well, these caps are a few years old and they were given to me by someone who had tried them in a DAC and didn’t like them and passed them on to me. They were said to be a matched pair and, indeed, when I measured them, they were identical. So I thought, perfect, matched V-caps, what could go wrong? Well…..

Ah, yeah that's a little different.

I have some Mundorf SO 2.2s that I can probably fit in. They are much larger than the Vcaps though. I will need to extend the leads a bit as these cannot go where the Vcaps did. How much additional lead length can I get away with before the performance begins to degrade?
