Psvane Teflon capacitors real or fakes?

These are great looking capacitors and supposed to be competing against the Audience, Rel, V-Cap, and Sonicap Teflon capacitors. A couple of my tweaky friends who have no end to new capacitors gave them a try and had one quit after a month or so, and with the wire cut off, no return possible. So they cut it open, yes they are curious, and according to them, the guts looked like mylar, measured like mylar??? Could these not be Teflon caps after all??? I open this for discussion with some of the tweaky electonic minds out there to get to the bottom of this. If they are not genuine teflon, I would not want fellow audiophiles to get ripped by another false claim. But to be fair, real verifiable data should be submitted here, no guesswork. I trust my friends, but I did not do the test, so I open it to other philes. Hey, I like a great deal too, but if it is not as advertised, I get pissed too. Take a look fellow philes, and lets solve the mystery....Jallen

If your dielectric is heating up AT ALL; it's because you are not using a heatsink, or not using one properly. Something as simple as an alligator clip, attached to the lead between the component being installed, and the point being soldered, will keep you and your components, safe. NO component should EVER reach the temp at which your are soldering.

there is no point to divert attention, I suggest anyone who has obtained his Psvane caps from reputed distributors like Grant Fidelity or Parts Connexion to have his caps' DF checked. There is no excuse for Psvane to claim that there are fake Psvane caps on the market since we know Grant Fidelity and Parts Connexion much better than Psvane.

Response to Grant Fidelity,

I will post pics when they arrive in the mail this week. They were not purchased from you, but pc in the last 6 mo. Thanks for your responses, jallen

Of course you are correct, Rodman. No component.

But what if you are servicing something with a teflon-insulated wire connected to a lug, insulated right to the joint? And if the factory used high temperature solder? Then the teflon might get hot, and that's bad.

I only intended to sound a note of a caution against a procedure discussed previously, about touching a teflon sheet with a hot iron.

Magfan, I think the arthritic feeling comes from CaF2 precipitating in the calcium channels of the neurons. What is left over of the HF trades up the activity chart until it bonds into an insoluable compound, as found in the bones. As you say.

All academic - as you also say, bad stuff.
