Dear Peter,
Guilty : I did not send back caps but I will do it.
The caps were used in AN electronics (Kit1 , Pre-Kit , Dac1)
whose components were upgraded but schematics not modified.
Voltage ratings were OK.
Temperature : here is the problem I think.
Yes Kit1 warms , and components have to endure it.
Otherwise you have to advise people the your caps do not endure ClassA Amps.
You say failure rate is minimal ;It is probable but the problem is that this default does not generate a failure but a subtle degrade.
And how many people do open their electronics to verify if there is
some oil on their new caps ?
So I propose to send you back some caps for analysis.
If you can exchange them I am OK ,but only with new model.
Greetings
Gilbert

Dear Gilbert,
This must have been very early samples of our caps, do you remember how long ago??
(Not an issue as far as exchanging them is concerned, by the way!)
We no longer make the copper foil caps with this type of seal, for exactly this reason, the silver caps on the other hand do not have this problem as they use mylar film not paper in oil.
It is quite true that when the seal breaks the cap's sound deteriorates.
Sincerely,
Peter Qvortrup

  I had severall orders in the last years , all by Philippe (AN France), the last was this summer. But we don't know how long components were on stock .
  For example I had some 0,22uF old and new model , and the last order
  concerned 0,015uF and I received old models, this value being certainly less demanded than 0,22uF.
  I fear I have not keeped them all , so I will return You what remains.
  Best Regards
  Gilbert

    Dear Gilbert,
    Send me what you have, or give them to Philippe, and I shall collect when I am in Paris next, make sure your details are with the caps and I shall send the replacements directly to you.
    Sincerely,
    Peter Qvortrup
