I would like to ask if the Obbligatos 450V 20uF-40uF caps are metalized polypropylene or the polypropylene foil? I was looking through you site but I did not see a clear information about it. Thanks you.

That sucks! Do you guys have any large value, 10uf or above, polypropylene or polystyrene but non-metalized versions? Something like thin foil and preferably with no oil?

No, sorry. I would if we could get them made but they'd be the size of a brick. There are some Russian polystyrene 3.9uf/160v on Ebay. That's the largest polystyrene I've come across.

Brian,

I was looking for information within your forum but I did not found, perhaps you might refer me to it. Anyhow, what I was looking for is the pattern how the sound changes in the 500V Obbligato MKP cap while the caps are break-in. If you do not mind then can you give me an idea what to expect after the burn-in and how long in your view it takes?

Rgs, Romy

When they are new they sound lean, fast and tight and take longer to run in than electrolytic. As they run-in the sound will become more relaxed and gain some 'bloom'. We have found takes about a month.
