I think that the Teflon needs to be changed to Polyester in this most prominant title lest it be misleading. Please do correct me if I am wrong.

Not sure how to correct the thread title as it was pulled from the first post. Maybe the forum mods can change it.

If you see our first post below - I have changed the title there.

A mylar dielectric has no place in high end electronics. It can be heard every time. Perhaps in auto speaker xovers it is passable. I am not convinced that it cannot be heard even there. Regards (while copper may make them sound better than regular maylar caps, IMHO they are still garbage)

I agree, John. Mylar is terrible, perhaps the worst-sounding dielectric out there, electrolytics excepted. I purchased four of these "teflon" capacitors to see what they're about. I have a good capacitance meter, so I measured them. The DF on these caps was 300-500X that of a good teflon cap. I sent the caps back saying they measure as poorly as mylar, and that I cannot imagine them being anything but given their small size.

I take John Curl's advice and never use anything but polystyrene and foil and Teflon and foil-and have been doing so for 25 years. BTW the new Solen Teflon and foils are terrific and fairly priced. They are also 1000v rated and can used in SE amps. Regards

That's my approach also. I've become quite sensitive to the sound of dielectrics and really don't like anything but teflon (preferred) and polystyrene. Polypropylene---I scrap or avoid these whenever I can.

Many years ago, Jerry Foreman of Precision Audio Supply introduced me to Teflons-he was a consultant to RelCap. He would get me hermetically sealed milspec teflons . As I remember .22uf600v were somewhere around $75. Frightfully expensive for the day, but the best you get for SQ. Regards

I feel safe in the knowledge that the same manufacturer claims to have made a perfect RCA 300b copy. not.

Quote from http://shop.grantfidelity.com/Psvane-Capacitors/:

"In short, according to the factory, Psvane caps are made with "Beryllium Copper Foil, the highest grade Dupont Polyester film as dieletric, with Teflon shielded tin tipped leads". They are not a copy of V-Cap; so they are neither real or fake V-Cap. They are simply another creation of high fidelity audio capacitors for audiophiles pursuing better sound."


As this are NOT Teflon-FOIL capacitors, to bring those Psvane caps only remotely in conjunction with real ("V" or whatever) TEFLON FOIL caps is - IMO - outright misleading.
As I see it this seems to be intended.

Would you trust a company that claims it's pronounced "pavane" cos they can't be bothered to correct the obvious typo?

And as I`m REALLY grumpy today (because of something what concerns attempts digging in other peoples wallets and what in turn has also certain things in common with the topic of this "sort of Teflon" capacitors) I`m going to add this to my previous post:

The mention of "Teflon shielded tin tipped leads" in the description (to sneak in the idea of Teflon somewhere) could maybe still pass through as a "refined" attempt to mislead uninitiated people to suspect that this caps might have something to do with real teflon film caps without outright lying.

BUT to print "Teflon Copper Foil" on the capacitor`s body (see picture in post #1) when the capacitor in fact is made of polyester / Mylar foil is clearly beyond any semantic "finesse".
This can`t be regarded as anything else than a scam. Period.
Sorry for the hard words but it must be allowed to call a duck a duck.

P.S.:
Don`t worry, I won`t rock the boat anymore than this.
I`m going to take a beer and try to cool down.
